Car systems 101

[Shawshanks]

I'm getting a 2005 4runner and want to upgrade the sound system in there. i'm aware of what brands are good (somewhat) and what to stay away from. currently in my 89' honda civic, i've got a kenwood deck and amp w/ mb quarts components and coaxs, love the mb's but also like the polks... in the new 4runner, i'm planning on running an alpine deck and amps and use polk momo speakers all around. i am more into clarity w/ a little thump but nothing that will rattle the neighbors windows. so i'm thinking about getting coax 6.5's in the doors and running something small like a 10" sub in a sealed or ported box. so questions are: with what i've suggested, would that be a good start? if the 6.5's say that their power handling is 80w contin at 4ohms, will a 4 channel amp at 75w x 4 @ 4 ohms be good enough to power the speakers and not damage them or perform less than ideal? the alpine deck says that it has 50w x 4 power, should i use the deck power or not and just get a 4 channel amp? again, i need simple and basic answers. i was reading a couple of the questions and responses, although very helpful and full of knowledge, some of it just went past my head.

i know i've got other questions and will probably think of them later, but at least this gets me started.

thanks in advance, i want to join the polk/momo family.

[AustinKP]

Sounds like you're on the right track. An amp at that power level would be just perfect for those speakers. Stay away from deck power since the 50x4 listed is peak. RMS will be around 15-20W per channel.

[neomagus00]

welcome to la famille! :) i like the setup you're thinking of, but consider using only front speakers, and if you can afford them (and, importantly, proper amplification), absolutely go with components.

a note on your sub: you mentioned you want a little bump, but noting big. consider a 12" sub. while it will be capable of being louder than a 10", that is easily controlled, and a 12" sub will be able to pull out the really deep stuff better than a 10". also, for what your tastes appear to be, a sealed box is likely the choice for you.

and an agreement with austin; if at all possible, always go with external amplification, because decks are weak and dirty :).

a 75 x 4 amp will probably be too much for 80W components. That 80W is quoted for the mid/tweet pair, so if you use a 4 channel to biamp (a good idea), you really only need a 50x4 amp.

finally, what's your budget for the project? we can make much better reccomendations when we know how much you want to spend.

p.s. if any of that sounds like a foreign language, just ask and we can clarify :).

[MacLeod]

Welcome to the club bro.

Components may be a better option than coaxials in the front for a couple reasons. Components use seperate tweets and mids so you have much better flexibility in placement and this affords better imaging and staging. Also, components usually have better quality parts and materials and this is especially true in the crossover. If however youre just wanting a plug and play system or dont really want the hassle of a more complex install then coaxials are fine.

Rear speakers arent necessarily a bad idea. Most purists (me included) dont like em cause they not only pull the stage to the rear but tend to smear the detail by having the same music hitting your ears at different times. However if you haul passengers around a lot and listen to CD's then rears can be a way to go.

An 8" sub will be ok but I prefer 10's myself. I think they offer the best sound quality and impact and since its going to be inside the car with you, you wont need much bigger.

Cant go wrong with Alpine amps and head units. Especially if you go with the Alpine V12 amps. But if youre going to be spending in that range check out the Polk line of amps. (http://www.polkaudio.com/car/amps/) Just as good but a little more rare.

[Shawshanks]

man this is the 4th time i'm typing this response, this is killing me...lol

thanks again for the warm welcome as well as the help, insight and experience on car audio information.

based upon what i've read i'm definitely going w/ a seperate amp for the door speakers. now what would be the pros/cons of getting a single 5 channel amp vs. getting 2 seperate amps (not factoring in space and price)? i'm looking at the ususal brands like alpine, jl, mtx, rock fos, etc.... but am i missing out on some lessor known brands at a lower price point but perform just as well as the big name brands? any brands to recommend? i'm looking to spend b/w $150-200 for each amp (if i go the 2 amp way), mostly looking on ebay for these.

since its a new car i really don't want to drill any new holes in the doors just yet, i haven't even received the car yet, still being shipped up from CA. but i'm wondering if there is a seperate tweet area on the doors near the side mirrors, if so then i'll go w/ seps for the front door and coaxs for the rear door. i heard the polk seps and they didn't sound as good as some of the other brands. i hope that they were set up incorrectly and they fix the problem, but the infinity reference speakers sounded great. i'll go w/ a 10" polk/momo sub in a closed box, something not too big so that i can still fit the golf clubs.

thanks again for all of the help and info. i look forward to reading more of your responses and getting ideas so that i can get my ride runnin and bumpin...

[MacLeod]

I actually prefer 5 channels and kick myself at least twice a day for not getting one. Crossfire makes a 5 channel thats 50x4 + 300x1 which is EXACTLY what Im running now with my 2 amps. :rolleyes:

5 channels are easier to install and take up less room but can be just as powerful.

Alpine makes this (http://www.crutchfield.com/S-7TRjSshu6L9/cgi-bin/ProdView.asp?g=120&I=500MRVF450) 5 channel but its not very powerful in the sub channel. I recommend getting a hybrid amp that is A/B in the main channels and Class D in the sub. This Kicker (http://www.crutchfield.com/S-7TRjSshu6L9/cgi-bin/ProdView.asp?g=120&I=2064KX7005) is one like that. Its very powerful, 70x4 + 420x1 provided youre using the MM2104DVC. This is the one I would recommend. MTX made a badass 5 channel but, alas, its been discontinued.

[Shawshanks]

Mac... thanks for the suggestion and i've been looking online at some of the kicker amps and impressed w/ what they've got. i guess what i need to do is look at the 4runner and see if it will fit, i kinda don't want to build anything, i want it to look as if nothing is in the car w/ the exception of a detach face plate.

besides watts and rms, what other things should i be looking for when shopping around for amps? i'm seeing x-overs, freq response, high/low pass, etc... now i maybe asking for something i may not understand, but i'll take my chances.

[neomagus00]

better to ask than make a mistake... i learned that the hard way a few times...

the features you'll need in an amp depend on the headunit and the amp's intended use. you'll be biamping, so you'll need a relatively complex crossover system on the amp. you'll need one pair of channels with a really high highpass (~3500 Hz), one pair that you can fake into bandpass (actually pretty easy - lowpass on the amp at 3500 Hz and highpass on the HU at ~80 Hz; that way you only need 2 preouts), and the sub channel of a 5-channel amp will have a lowpass (and a subsonic/infrasonic highpass is good here too).

the key is to find an amp that has separate crossovers for each pair of channels.

the frequency response of an amp is irrelevant, they're all essentially the same here.

what model headunit are you looking at? or, if you don't know, what's your budget and needs?

[MacLeod]

The thing with great crossovers on amp is that they tend to make the amp cost over $500 and you really dont need them.

If youre going to run rear speakers then you definitely dont need them. Just use the supplied x-over that comes with the speakers.

If youre going to go with fronts only then I suggest bi-amping. I would also suggest the MMC6500 component speakers which are the best speakers you can get for that money and their x-over is bi-ampable so you would have to worry.

Other than that, the only considerations in buying an amp is power requirements, size and cost. All amps within the league of MTX, Rockford Fosgate, JL Audio, Hifonics, Kicker and such are going to have good build quality and make clean power. Dont let anybody talk you into buying a certain amp cause it sounds "warmer" or has "smoother highs" cause they all sound the same!

[Shawshanks]

Neo... thanks for the info. maybe a dumb question but does "bi-amping" mean that i'm going to run two seperate amps or does it refer to a 5 channel amp and doing something special w/ it? as for the head unit i'm leaning towards either the alpine 9847 or 9851.

Mac... thanks for the heads up on getting sukered into "warmer" or "smoother highs", i'll definitely keep that in mind. sometimes i may make things more difficult than they really are.

does anyone know of any websites that give objective reviews on car audio equipment?

[phuz]

I've got an 05 4Runner Sport, and yes, it does have a seperate place for the tweeter(s). Components would work well for you. I'm about to change the jumpers on my crossovers to lower the level of the tweets because they are high up on the door, and it's a bit overbearing considering that the 6.5" driver is down near the floor. Thats something you might want to keep in mind when you do your install.

Factory speakers are 6x9, with a seperate tweeter. I put some 6.5" components in with an MDF adapter. Mounted the crossover(s) in the door, and viola.

Rear door spealers are 6.5" I think. I dunno, I didn't do anything with em. :)

My amps are under the front seats. If you want to do that you'll have to remove the vents from under the seats, no biggie. People in the back don't need heating/cooling on their feet. ;)

Doubt you'll be able to fit a 5 channel amp under there though. heh

A single 12" sub will do fine, in fact mine is overkill. A quality 10" will do.

Keep up with this thread plz. I'd like to see what you do with your 4Runner.

[neomagus00]

yeah, mac, that was good advice

shawshanks - bi-amping means that, instead of running components (which are just 2 separate speakers instead of them being mounted together) off of 2 channels of an amp and running that through an external crossover, you run each speaker (2 mids and 2 tweets) off its own channel. this makes the setup infinitely more tunable in the tweeter-loudness area, which phuz says is a concern in the 4runner (and is a definite issue with the polk components, too; the tweets are very loud).

like phuz said, it's unlikely that you'll be able to fit a 5 channel amp anywhere but in the back somewhere... i dunno where you'd put it, i've never done an install that it didn't go in the trunk.

those HUs will do you well; i can't see a difference between them in specs, so i guess aesthetics is the key here. they do have bbe though, that makes me happy.

[Shawshanks]

the 4runner is finally in and i'm going to pick it up tomorrow!!! :D the thing that sucks is that i'm going back home to hawaii for at least a month and i'll only enjoy my new ride for about a week and i won't be able to put the sounds in till after i get back, but oh well....

phuz... i'll have to check my 4runner, i've got the sr5 w/ the stock system so i don't know if mine will have that seperate tweet section. good call on the tweets being too high and maybe a bit overbearing, i'll definitely keep that in mind. but definitely i'll keep this thread going for as long as i can and keep peeps posted on what i'm going to do.

neo...ahhhhh!!! that helps a lot in trying to understand more of this technical stuff and helping me try to make the right decisions when hooking up my system. i guess w/ the time back home, i'll be able to go to several car stereo shops and do some testing w/ seperates and see which ones would work best and give me the sound quality i want. as for the hu's, i've always wanted an alpine since i was in high school and now i can get one. i've always had like pioneer or kenwood, not bad decks but there was just something about alpines that makes me go oooohhhh, aaaaahhhhh...

can't thank you guys enough for the info and help. much appreciated!!!!

[MacLeod]

The short version of bi-amping is you run your tweeters off the front channels and the mids off the rear channels of a 4 channel amp.

Whatever you do, find a place to listen to some MMC6500s. They are excellent speakers and can easily compete with speakers costing much much more.

I know what you mean about Alpines. Only the "cool" people had them when I was in high school so now I wanna be cool too! :D

[Shawshanks]

I just got the 4runner today and just my luck, the transportation company who shipped it up placed a deep gauge on the driver side door below the key hole about an 1.5" long and down to the bone. needless to say i was very livid.... well the claims person said to take it to get estimated and it will cost almost $900 to get it done, good thing i'm not paying for it. that sucks and what a way to start w/ the new ride...

anyways i noticed that there are seperate tweets on the door and i'm going ahead w/ seperates in the front, coaxs in the rear door and a sub in the back. when i looked underneath the front seats, it doesn't seem like there is much space for an amp. does anyone else think so??? so i'm going to have to do some exploration and see where else i can put the amps.

has anyone ever heard (by brand and sound) of MA audio??? are they a good brand? does anyone have any articles saying anything about their products?

[phuz]

That sucks about your door man, glad its getting fixed though.

Yeah all 4 runners have the tweets, even the most basic SR5.

I've got a Zapco iForce 250 and an Alpine MRD-301 under my seats, and I know bigger amps will fit. There is more room than you think. Like I said before though, I doubt a 5 channel amp would fit.

[neomagus00]

their site has a forum; at the moment, they're redoing it, but this (http://www.maaudio.com/sub/) will get you to the old version of the site. i glanced through and noticed two things - one, nearly everyone runs their subs at peak instead of rms ratings (running a 400 WRMS sub at 800WRMS!) and two, they seem to be very spl oriented. other than that, i've no idea.

[MacLeod]

MA Audio is decent stuff. Yes they are pretty much a strict SPL company. Their subs handle a lot of power and their amps are pretty hefty as well. As for SQ, eh.

[Shawshanks]

what does "SPL" and "SQ" mean??? Does "SQ" mean sound quality?:confused:

[neomagus00]

yep, sq = sound quality; until you get into relatively expensive subs, volume is sacrificed to achieve this (generally).

spl = sound pressure level; these are the anti-sq subs. they sacrifice quality sound to make it louder. however, in these, as you rise in price you only rise in volume, sq often continues to drop (again, just a general rule).

then there's sql, sound quality level. these attempt to make really loud but really clean sound. a true sql woofer is generally very expensive (case in point - eclipse titanium series).

[Shawshanks]

thanks again for the info Neo... always good to know stuff like these before hand.

Hey Phuz... you said that you also have a 4runner and that the amps would fit under there, but i went to look at it and it does seem kinda tight. for some reason i see wires under both seats even though the only electronic thing on my seat are for the lumbar adjustments. how did you work around that? do you also have the wires under your seat? trying to figure out if there is another place to mount the amps? i want to keep them hidden someplace and not out in the open. i really don't want to attach them to the sub box or even build a casing for it in the back. any suggestions?

[phuz]

The wires are for the lumbar support, and some sensors. Yes I have them. Once you remove the vents from under there, you will notice more room. That is really the only place I could find that would keep em hidden. There is absolutely no room under the rear seats.

Don't ever mount and amp to a sub enclosure. :) It's bad.

I didn't look into any other options since mine fit under the seats. I'm sure there are lots of options in the back. Mounting them to the back of the rear seats, or creating a false floor or wall for a clean install.

Also, check where your jack is. You might be able to squeeze one in there behind the side wall in the back.

[nil83r]

Hey shawshanks i like your setup idea u know why it reminds me of my setup i got the following setup
Head Unit: CDA-9833 Bass Engine Pro CD / MP3 / WMA Receiver / Changer Controller
Subwoofers: 2x MM2124 Polk Audio Momo 12 inch
Rear Speakers: DC650 Polk Momo 6.5 inch coiaxial loudspeaker with external crossover
Front Speakers: DB6500 Polk Momo 6.5 inch two way component system with external crossover
Subwoofer Amplifier: Alpine MRD-M501 V12 AccuClass-D Mono Power Amplifier
Front & Rear Speaker Amplifier: MRP-240
Alpine I-POD Module Link
this system is awesome man recommend anything in it

[MacLeod]

Umm, do you have DB speakers or Momo speakers?

[nadams]

Why say you? I've had mine mounted there for 3 years and 3 different cars (same box/amp combo travelling throughout) and it's been fine...

[MacLeod]

Maybe vibration could affect them but I had 3 Coustic amps mounted to a box for a pair of 12" MTX Terminators for about 3 years and never had a problem.

[Shawshanks]

Hey Nil... thanks man, i hope that i can make it happen. right now i got some inifinity 6.5 coaxs from fry's that were only $50 and now i need to get the front components. i'm going to slowly build my system. hopefully some of my friends back home will give me some ideas on how to mount everything and that they can hook up some deals for me.

has anyone heard of "planet audio" amps? are they any good?

[neomagus00]

they're big, and they make power. nothing special, as far as i know, but not too bad either.

[MacLeod]

Yeah, Planet Audio is decent stuff. Worth looking into.

[audiobliss]

Shawshanks, how's this coming? Have you pursued this any further? I'd be interested to see what it is you'ved decided to do and how it's working out for you.

[Shawshanks]

Hey audiobliss... right now things are on hold while i'm back home in hawaii taking care of some family business, although i'm still gathering some info on possible products going into the 4runner. i've decided to go w/ a better HU, the alpine 9853. i still need to look at how and where i'm going to put all this stuff in and still have it look stock. where to put the amps is my biggest issue, i don't want to hook it up to the sub box or on the back of the back seats. i've already got the speakers, inifinity's for the doors and 10" momo sub. when i get back to portland i'll get all of the other stuff and put the bad boys in. one thing w/ getting a new ride, there are all of these cool things i want to install. when i get everything done, rims, stereo, i'll post some pics.

thanks,
shawshanks

[Shawshanks]

hello all... ok i'm back in pdx and starting to get back into the swing of things. after searching for areas where i can house the amps, i've decided to go w/ a false floor in the cargo area option. my buddy is going to build the floor this weekend so hopefully i'll have some photos of the build and post it. my buddy also got a new truck, tacoma, and wanted to sound dampen the whole truck but didn't want to spend an outrageous amount for dynamat extreme stuff so we found a sub. it has the same characteristics as DM w/ the aluminum front and sticky rubber bottom and when we tested a small piece on a cow bell, it worked the same. anyways we paid $75 for a roll that was 36"x75', that a lot of roll but i guess i could double the application and still have plenty left over. the product is called "peel & seal" and u can get it from a roofing material company or home depot or lowes.

now back to the stereo stuff, this is what i'm going with; alpine HU 9855, infinity kappa 6.5 components in the front and 6.5 reference coax in the rear door, polk momo 10 sub, 2 amps. now the delima i'm having is what kind of amps should i go with, i've narrowed it down to 2 brands, alpine and phoenix gold. the alpine amps are MRV545 and MRD605, the PG amps are xeon X200.4 and X400.1, they are all around the same price. so which ones would you go w/ and why???? i'm planning on getting them online through ebay b/c they are way cheaper and some of the sellers seem legit but no physical store near where i live. so the question is, has anyone had any good and/or bad experiences purchasing stereo prods online from ebay? has anyone had probs w/ DOA's? etc....

thanks gain in advance for ally of your suggestions and input, greatly appreciated.

[MacLeod]

Id go with the Alpine. Ive always really liked the V12 amps. Also the PG amps are fully regulated and those arent my favorites.

Have you listened to those Infinity's? I really dont like em. I had a set in my truck before converting to Polk and I hated them. Infinity speakers are inherently very bright and when you throw in a bunch of glass windows and hard plastic dash panels, they can be pretty harsh especially if you listen to heavy metal.

Just my $.02

[audiobliss]

Hey, man! It's great to hear from you again and to see that you're still planning on doing something with your 4Runner! Hope you had a great time down in Hawaii!

Sounds like you found quite a deal on the sound deadening material. I bet it'll work just as well as Dynomat.

I, too, am disappointed that you've decided not to go with the Polk components. I really do believe they're the best components you can get for the money. They should really sound much better than the Infinity's. Like Mac said, Infinity's are quite bright. However, if you've listened to them (with all the different kinds of music you like to listen to) and seem to like them ok, then you just might be satisfied with them. Whatever your ears say are right.

I would also go with the Alpine amps. Not because the PG amps are bad, but because Alpine just has a better name, reputation, and probably record. They make really solid, good quality stuff. You can't go wrong with Alpine.

I would never buy anything from e-bay. For one, you always have the risk that the seller is running some sort of scam. You may not get anything, a seriously cosmetically damaged piece, an internally damaged piece, or a refurbished piece. Also, even if it is just fine, but happens to break later on, you will have no warranty. If you go with Polk stuff, they have a great warranty and great customer service. However, (no matter what brand you buy), you'll have no warranty if you buy through e-bay. So, basically, buy at your own risk!

[spwuinmk67]

The peel and seal should be fine, others on the forum have used it with no problems, you'll be surprised at how much you use. I'd put extra on the door panels, and door skin.

The infinities aren't bad speakers at all, I think you'll be happy. A buddy of mine has all infinities and they sound pretty good, not too bright. Every car is different, so the speakers will sound different from mine, to yours, especially to the sound room. If they get too bright in the front, use the tweeter attenuation to drop it down a bit. Also if you bi-amp them, you will have better luck getting them tuned, but it is more work.

I wouldn't buy any stereo equipment off ebay either. You get absolutly no warrenty, and if something happens your f'ed. Even if you find an online store thats maybe not authorized, but offers a warrenty though them, that would be better then ebay. But shop around. www.sounddomain.com does price matching, so if you find something they carry, anywhere else for less, they will give you a closer, or better price. They are authorized as well.

[exalted512]

I'm a little late, but yea, the reason why dont want to mount amps to sub boxes is because of the vibrations. You might be lucky, you might not. I say better safe than sorry. Its not something thats going to happen right away either. Itll take a few years and by then your warranty is gone. Also, if a thief gets into your car, all they gotta do is snip the power and speaker wire, pull out the rcas and rem and bam...free amp, box, and subs all in one convenient package.

Order off of ebay if you like, some sellers do offer warranties, granted they will not be from the manufacturer. Just make sure to buy from someone with feedback and read the description entirely...you know, the whole common sense thing;)
-Cody

[Shawshanks]

hey guys... thanks again for the help. now u guys have got me thinking about getting all polk speakers. :D i'll have to go and listen to the momo's again and compare them w/ the infins.

i guess it is buyer beware when it comes to ordering car electronics off of ebay, the pricing is the kicker and saving hundreds of dinero now vs. spending more later is the delima... i'll have to think it over.

well i need to get all of my stuff soon. when i do then i'll install the sound dampin product and lay all the wires for the amps, speakers, false floor, etc....

wish me luck...

[neomagus00]

good luck! and ebay = bad for car electronics unless you buy from a big, reputable seller... also check out paypal, it's kind of a hassle but I believe that it helps ensure fairness (check that claim before you go using it, though)

[swerve]

i bought my hifonics off ebay for 535 from indoaudio..

:D

[MacLeod]

I will always be preaching about buying from authorized dealers. Ive just heard way, way, way too many horror stories from people that bought crap from what equated to some dude selling stuff out of the trunk of his car!

[Shawshanks]

ya i've been checking out some of the postings and what company's are selling what on ebay... i've seen indoaudio and couple others like locust, etc... i've been reading some of their feedback from people and reading all of the fine print they've got on the website, but yes its a gamble and hopefully if i do decide to get something off of ebay, my research will make it easier.

oh, now i'm contemplating going w/ CDT speakers for the doors. i've heard some good things about them but don't know anyone here who has them so that i can listen to them and judge them for myself. but i hope to get all my stuff w/in the next month or so and get the project going and done.

has anyone heard, seen, have, or know of what brand(s) are best when it comes to putting a clear plastic coating on the front hood and bumpers of cars? i'm thinking about doing that for my 4runner b/c here in pdx, they use pebbles during the winter to provide traction and that stuff isn't really cleaned up well and tends to fly around and create chips in your window or hood.

[Shawshanks]

Hey all.... first off a congrats to macleod for getting those new SR's, they are sweet... but anyways after many debates and looking into some other brands, what do u guys think of the MTX -7804? i've read some good things about that amp and that they are working with or part of xtant, correct me if i'm wrong... plus could someone clarify something for me? i've changed my door speakers to CDT's and the rms @ 4ohm is at 120-130watts, if i were to go w/ an amp that puts out 85w/ch/4ohm, will that damage the speakers in anyway? am I under powering the speakers? should i get something that is closer to the watts given by the manufac?

so i'm getting closer and building things very slowly but getting there. will keep u guys posted and eventually post pics when if finally get my ass and money in gear to get the rest of the stuff.

[exalted512]

its 85wx2 channels???

[Shawshanks]

would be 85w x 4. should i get an amp thats putts out more watts? closer to the rms of the speakers?

[exalted512]

well if you bi-amp them youd be giving them exactly what they need. Or did you buy sets?
-Cody

[MacLeod]

MTX amps are awesome. They are owned by Mitek which also owns and builds Xtant.

If youre getting an MTX amp rated at 85x2 you can bet its actually putting out closer to 100 per channel. Either way, its best to get an amp thall make power closest to the speakers rated handling. Using 85 watts on a 120 watt speaker wont damage it but it will make it more likely youll overdrive the amp, clipping it and the resulting 170 watts itll shoot out may damage the speaker.

Bottom line would be that amp will be ok as long as you use common sense with the volume and set the gain properly. And remember, MTX amps are very underrated.

[Shawshanks]

sweet... glad i went to this site and there are peeps here that know their stuff.. great to hear that and it makes my decision a bit easier. again, can't thank everyone enough for their insight and input.

[Shawshanks]

Ok all.. this is what i've got so far.

MTX 7804 (4 ch amp)
MTX 4501 (mono)
CDT CF61 6.5 components
Infinity reference 6.5 (rears)
Street Wire Combo Block
HU installation kit

this is what i still need and/or arriving w/in a couple of days:

Eclipse HU CD8455 or CD8445 (still deciding and any input is helpful)
1/0 Amp kit (any suggestions on good brands, w/ 2 amps do i need the dual amp kit, etc...??)
Knukonceptz Krystal Kable 4m 4ch & 2ch RCA's (shipping)
Knukonceptz Karma 12AWG Bi wire (is 12g good enough? for the seps up front, shippin)
" " " 12AWG Speaker wire (shipping)
Polk Momo 10" DVC sub (shippin)
Yellow top battery
Battery terminals

Do i need caps? anything else u guys can think of that i may need?

the false floor and sub box will be custom built, hopefully they will come out looking good. will be installing sound dampinin material throughout the truck. this maybe a long couple of days when i get everything set and of course I WILL POST PICS during the install and when completed.

thanks

[audiobliss]

Man. That's gonna be one awesome system, for sure!! Can you remnind me what this is going in? Was it a 4Runner?

[MacLeod]

You wont need a cap.

As for which head unit, just pick the one that has the features, appearance and price that most closely matches your needs.

thanks for the responses... audio, ya its a 4runner and i'm get excited about getting things going. the plan is for us to build the floor, sub box, panels to fit the 6.5's in the door properly first and i'll get pics of those when we do them. then when the HU and all other stuff comes in, we'll gut the truck and install everything and put it back together again like humpty.... the HU is gonna take a while, my buddy back home in hawaii owns a stereo shop and hooking me up w/ a great deal on the eclipse, so i don't mind waiting.
