[low95ryda]

can anyone help my design a box for a 1995 fullsize chevy reg. cab pickup? i have been working on this truck for 2 years and now i'm doing the interior in my daily driver i have 4 MM2124 and i'm running a Directed 2400 i love it so now its going in the truck. BUT i not sure if i want to go with 2 or 4 2124 s ,the good thing is i'm short so i dont need to have the seat all the way back. can anyone help me out? thanx Nick

the limiting factor will be exactly how much space you're willing to give up... with four subs, you're probably going to have to build a box that will cover a ton of space... i'm not familiar with that vehicle, so i'll let the truck people give you more advice, but 4 12s in a truck sounds like a lot to me...

Ive driven mostly trucks in my life and can tell ya, 4 subs will be a bit too much unless bass is all you want to listen to.

If SQ is your primary concern, then a single 12 would be plenty in a regular cab truck.

If youre wanting to be loud then go with 2.

4 would just overpower everything and would sound kinda bad in my opinion.

dude, don't you know that car audio is all about the BASS!!!!!!

[MacLeod]

Nah, car audio is all about how cool it can make your car look! Sound performance is secondary.

well i'm trying to have a bad ass ride and sound, so i've decided to go with 4 2124. so now the ? is seeld or ported? thanx

[MacLeod]

Sealed. Polk subs are designed to work best in a sealed box. Plus theyre the easiest to build and sound better.

[neomagus00]

if you're going for volume, ported would be an okay option, just be careful with your measurements and so on...

since the polks like sealed boxes, they'll be happy in 4th order bandpass, too, which are very large and very loud enclosures that don't sound very good...

thanx guys, went and got the wood today going to start building it this weekend. i'll try getting some pics too. later

[low95ryda]

well i got the box built last weekend i only went with 3 12's in a seeled box sounds awsome mon i'm going to have the db tested see how loud it is, but i only have 1 problem and it stsred on fri. when i play it to long my amp and cd player go on and off and the amp goes in protect anyone got some advice? i'm betting the battery is about shot but i wanna get a yellow top anyway. My buddie has my dig. camera i'll get some pics it looks sweet.

My basic rule to follow is that your charging system should be setup to carry the supply of your equipment . I run a 140 amp altenator to run the ignition lights and truck itself. I have a 200 amp leece neville altenator to run my stereo system. From what I have been taught you should'nt draw more then 80% of your altenator's capacity. Your battery is storage and also used as a filter device in a sence. I have seen comp vehicle's run a altenator and a few 1 farad cap to run there audio system. My system consist's of 2 c300.2 and a c500.1 I have my voltage set at 15.2 and at full load the voltage maintains with no drop. Power cable is a big concern also due to line loss and resistance. I run welding cable very fine stranded 0/2 to each amp. For your truck powermaster makes 200 amp altenators worth the up grade . The better and stabil the voltage and current supply the better your equipment will perform.

Also when amplifier's strugle for power it creates excess heat. I had a directed amp before it did'nt like a 2 ohm load either. Some people like the amp but after alot of research and tech support I choose polk being they stand behind there product and all of my speakers are polk figured they test there product with there product. Ebay has awesome deals on polk amp's and subs that is where i got mine. If you do upgrade the altenator make sure you run a heavy gauge wire from the charging post to the battery that is another overlooked area .

the cones seem dusty... the yellow accents are an interesting touch, though...
