View Full Version : Got laughed at today...
I recently obtained two Infinity 10' subs cealed in a box. I intend to use these for my home theatre, vice the car... The problem is, how do I do this?
I asked someone whom of which I consider to be knowledgable in regards to audio, and they said its almost impossible to convert them over to home audio. I then ask CC and BestBuy employees who have no clue its even possible.
So, I figure if anyone would know how to do this, it would be the TRUE audiophiles! So please!! I am in dire need to know how to get these pups roaring.
I have a good idea on what needs to be done, but not enough to post here..... so if anyone has any instructions on what to do, and what I need to buy in order to make this work, please respond!! Thanks!

Choose ported or sealed and build a box on par with the internal volume that Infinity recommends. Get your amplification lined up, beit a plate amp, old receiver, seperates, and you are golden....
Why could you not use them at home? Faakin' idiots I tell ya, how does the woofer know if its in a trunk or living room? Build that sucker, and then bitch slap everyone that laughed at ya......
Cheers,
Russ

I recently obtained two Infinity 10' subs cealed in a box
Are they sealed in a sub box? If not that's probably your first step. Then get a 2 channel amp and a Y spliter out of the LFE and some speaker wire and off you go. It would also be nice if the subs were 8ohm, but most likely they are 4?
Quite honestly, I got these subs at a steal of a price. Both of them sealed in the appropriate box for $105.00
The question I have is this. I have a reciever a no longer use, a JVC, but I truely dont believe it supports 2-4 ohms. (yup Nascar, they are 4) It is however, a dedicated towards two channels. Would this work, as I am a cheapskate and really am hesitant to plunk down lots of cash.
I also would need something which sends only low octave signals to the subs, how could this be implemented IF I use the reciever? A follow up question would be, could I hook up this reciever to the main one without trouble?
Sorry for my ignorance, I promise its not blatent! haha Just a fledgling to this audio world. Thanks for the help thus far guys, making me feel better already. :)!

Does your main receiver have an LFE out? Does the old JVC have main l&r inputs?
Thats a yes on both accounts....

OK Use a Y spliter out of the LFE and run the 2 cables into the main in l&r on the JVC receiver. Then run speaker wire from receiver to each sub and you should be ready to go?
Nascar, ok a good picture is beginning to form now! I thank you for your patience!!! Will go out tomorrow and purchase the splitter. My only question now would be, how would I omit only low frequences to these subs?
nascarmann
06-18-2002, 08:26 PM
The LFE out of you main receiver is only Low Feq. So that's all the old JVC will be getting from the main rec. Then it will send only low frq to the subs.
Ah, thought that was the case. Just making sure! Tomorrow will be the big testing day. Thanks again Russ and a big one to you Nascar. Will try it out, hopefully all will go well. I am in your debt :)

If you want to run them mono, and want an 8 ohm load, Wire from the + on the amp to the + on sub1. Then wire from the - on sub1 to the + on sub2. Finally, from the - on sub2, to the the - on the amp. 8 ohm load from 2, 4 ohm speakers......
Let us know how it sounds, I used my single 10" Polk sub for my truck in my home theater for a week, worked like a charm. (using a NAD receiver to power, with LFE input from my HT receiver...)

I found some specs of Sub that may help...
Just trying to help
Ok, got the Y audio splitter and an extension cord so it will reach. Uhhhhhhh.... now what....
I have it coming out of the main reciever *Onkyo*....... but Im not sure where to put the other ends....
nascarmann
06-19-2002, 11:05 PM
OK now....What the hell is the extension cord for? Do you have an extra pair of interconnects to plug into the Y adapter?
Ok, I assume you were talking about this?

If so, then I purchased the wrong thing.

Y out of the LFE on the Onkyo. 1 pair of interconnects from the Y to an input on the JVC (do not use the tape loop or phono), choose AUX, or CD....
Wire up the subs to the JVC, select the source you chose earlier (cd/aux), set the volume, and you're off.....
Cheers,
Russ
Russman, sounds simple enough. Will try it out right now, I have a funny feeling I got the wrong Y cable though..
Yikes
A follow up:
Im incredibly sorry for my display of ignorance throughout this thread, just one of those people that need step by step instructions.
I pretty much could gather what I needed but stupid me purchased the Y audio CABLE and not the splitter. I knew something just wasn't right.
Im extremely confident now that things will be a go tomorrow. I dont know where to begin thanking you guys! This has saved me a **** load of cash. If you ever stop by near southern VA, let me know and the beers on me. ;) Thanks,
Tomorrow I will post the results of all of this.

Where is S. Va. If it's SW Va I'm right at you. Kingsport, TN. I can drink a lot of beer!:lol:
Im roughly 5 minutes from Williamsburg. So if you ever come by and visit (possibly on a trip to Busch Gardens or Water Country), just announce it.
hehe As long as your beer is cheap! haha

Since I have sold my PSW350s, and I am waiting for SVS to start selling the PC+ series, I have an interim sub set-up that is similar to what you are trying to do. Here it is and it works just fine.
start with LFE jack at receiver
add one Monster Y splitter
add two Monster sub cables
add one Harmon Kardon hk870 amp with RCA inputs
add two New Advent Loudspeakers stacked sideways
mix together and voila - homemade sub!
The LFE jack only sends low frequencies, so don't worry about filtering, etc.
The gutsy HK amp can easily overdrive the Advents, so I have to be careful on overall volume, but they dig pretty deep (35 Hz) and have decent output.
It's fun reliving the 70's - I just don't want to stay there 4ever.

Hmmmmm....... Got the Y plug out of the LFE, interconnects on.....all aligned as they should be. both subs in the left and right are a go. No sound coming from them whatsoever.
Hmmmm just got a new outlet and ever since then my system sounds like ****. Hmmmmm. New problems
aaakkkk

Which input on the JVC did you use? Hate to ask, but is it selected? Is the JVC on? You turn the volume knob any? Make sure a 'tape monitor' or 'muting' switch isn't flipped, and you should be done with this deal....
Cheers,
Russ

Where are the interconnect plugged into the JVC? Make sure where they are connected(cd/aux ect.) that's what you need to have the JVC playing?
Russ, Nascar...all is set...... sorround is on, there should be no obvious quarks that I missed here. The interconncets are plugged into the CD. The knob is turned up with midnight option to boost. All speaker A and B combinations have been attempted. All connections secure and as they should be.
Im not using the JVC anymore, going with the Pioneer vsx d509. I dont think this should matter much, will swap out shortly to see however.
The only thing I can conclude at this point is that this reciever simply wont do 4 ohms. I have yet to wire it as you suggested Russ, perhaps thats my next step.
Messing with it right now, will be back shortly. Arggg, I think Im going to go bald early because of this.. lol

Just a thought.... you're using the LFE out on your main amp... but is it turned on? this could be the problem. With both of the recievers I have bought in the past 5 years had to have the LFE turned on either via OSD or a switch...
CGravil, yes it was on. I made sure of that. ;)
I would like to take this moment to sinceerly thank all who have given me advice on how to hook this up and to make it all possible. Im sure it has been rather frustrating reading through this obvious newbie fiddle around with the system.
However, there has been a strange turn of events. I actually took my Onkyo back today, just within the 30 day limit might I add. Though I highly recommend the reciever to anyone, this low-end JVC reciever powered my polks better. Though I must say the vocals arent as detailed, its a sacrifice I was willing to make.
Its just too much of a tease to have 4 more channels open for use with only 2 speakers being ran. Because it looks as if I will be only a 2 channel user for some time now, I saw little need for that reciever.
I may end up selling the 2 Infinity subs (with box/sealed) here shortly, thats something I will contemplate further. I am simply worn out with spending large sums of cash on audio, its seriously becoming an addiction that is growing much faster then my pocketbook.

Some one here said it I don't remember who...
I'll take a good two channel setup over a half assed 5.1 anyday of the week it's good "sound" advice

the quote was Troy's... go BDT
Oh and let me know if you do sell those Subs.... I've been looking for some car subs
Impressive system you have there Cgravil, Im sure all that cable and high end vcr/dvd players really make your system sing. Sure as hell wish I had the cash to replicate that type of equipment! haha
As for the subs, I spent roughly $150.00 on the whole deal, that includes shipping. Im not looking for a profit here, just to gain what I spent. . But before I consider selling them I have to see what condition they are in first. I have yet to rev them up and if I do sell them, I dont wish to sell a defective product.

it takes time. Start with a nice 2 channel. build it up. Watching movies in a GOOD stereo setup is better than a Crappy 5.1, I will promise you that. I got a really nice deal on most of the equipment, but I also had been saving up for it.
It helps that I have an unlimited supply of RG-6 Coaxial cable. That made all of the Component, Composite, and Coax-Digital Cables very easy. Ends and Soilder and a little bit of time.
Add things abbit at a time. I had good cables, the VCR, a DVD player and a CRAPPY reciever<RCA... man it was the bomb!>
Then I upgraded the reciever, and then the TV.
My DVD player mysteriously broke around the end of it's extended warrantee, and since CC didn't carry that brand of DVD any more, I got to get a new one and purchace an extended on that... Funny how that worked out.
Baby steps man... A wire or two here, a component there. and don't forget a good remote to control it all.
