system help ?

i have a few questions for you smart people !!!!! first off i have 4 audiobahn 15" aw150q subs. they are 600 watts rms per sub single 4 ohm voice coil. i want to build a box to fit in a 1991 chevy caprice classic for the four subs but i dont know how to calculate the required air space for each sub.if someone can tell me how or calculate it for me and give me the dimensions for each chamber i would greatly appreciate it....i am going to build a basic square box with two subs facing the rear(tail lights) and one in each side facing the wheel wells. the box will have 4 seperate chambers........

the second question for now is what kind of amp should i use to run these four subs i dont really want to run multiple amps..one amp if i can...

ANY SUGGESTIONS ON WHICH AMP WILL KICK THESE SUBS?????????

if i wire the subs to a single channel amp how would i do it ?and what ohm rating would i be at?? i know if i wire two subs + to + - to - i will get a 2 ohm load but if i run the 4 + and 4 - what will i have???

PLEASE HELP YOU GUYS HAVE BEEN HERE IN THE PAST TO HELP ME I HOPE YOU CAN HELP ME AGAIN.............THANKS A BUNCH YOU GUYS !!!!!!!!

First off you can run the subs into either a 1 ohm or 4 ohm load.  Your best bet sound wise would be to find a class d monoblock amp that can handle a 1 ohm load.  You would achieve this with a parallel wiring scheme, basically meaning you connect all the positive terminal on the subs together in a series and run it to the positive terminal on the amp.  It's the same for negative.

As for box size you'll need anywhere from 1.25 to 2.5 ft of airspace for each sub.  Now considering this is being done in the trunk of a car, even a large car like yours, you might want to consider facing 2 subs on each of opposite sides of the box. (2 front, 2 back)  Building the box you're speaking of would require more space and might be pretty tough to fit in the trunk.  Just think, with a mounting depth of about 9 or 10" and a width of 15", your box would need to be at least 55" wide.  I don't know offhand how wide a caprice trunk is but i'd bet that's pushing it.  As far as for the amps there's lots of good ones out there.  Amps are just like beer, they all get the job done.

Ok this is all on you.  First off if you're on a budget this is a good bet.  A lot of the hardcore installers and such will tell you that boss is garbage and whatnot,  not to say that it is the best quality in the world but it sure isn't the worst.  I will say that I have seen boss amps blow up on a few occasions.  I will also say that I've seen JL, Fosgate, PPI......just about any brand there is blow up.  The deal with boss is that you'll have to be more careful with wire guages and making sure you're getting enough voltage to the amp than with some more pricey models.  Some of the loudest systems ive ever heard have been boss, usually because people can actually afford to buy systems that hit 150db and up.  I'm not too fond of boss subs personally but you already mentioned having audiobahn so you're on the right track.  To sum it up I'd say if you can afford an $800 Orion amp then get it, otherwise go with boss for 1/4 the price.

Also you might want to look into getting 2 amps to push 2400watts of subs.

what about trading the 4 sub idea and going for 2 15" 4ohm dvc subs you would still wire together to get a 1 ohm load right??? im only looking to spend around 3 or 350 on a amp........i can trade these subs for 2 dvc 15's right now plus that would solve the diemna of building such a big box right?let me know what you think....

Wire them up like that.  Trust me those two 15's will rock a caprice.  Build a box with 2+ ft of airspace each and they'll quake.  Unless you're planning on winning comps that's all you'll need.  And I hope you have a component system or are planning on getting one cause you'll need it after adding all that bump.

how about a audiobahn a18001dq will that amp work for this setup?either with 4 or 2 subs ? i know its only 1800 watts but its hard to find one at 2400.let me know ..

what would happen to the ohm load with 3 single 4 ohm subs wired to a single channel amp? the audiobahn a18001dq? just a thought......

1.333 ohms....a 2-ohm mono stable amp MIGHT be able to handle this load but most likely you'd have to get one that can do a 1-ohm load.

If you're gonna have 4 subs you can get two JBL BP1200.1's and hook up two subs per amp, for 2400 watts RMS total.  But the dual amp setup won't work for 3 subs unless the amp's are the same make and model and can be hooked up together to give a single output channel that's the combined power of both amps.

those are the 4-ohm voice coil DVC subs, right?  Assuming that's the case, you'll wire them up like this:

If they are actually SVC subs, you can still use that audiobahn amp cuz it's 1-ohm stable.  3 of the SVC subs would be hooked up like this:

can someone recommend an amp for these subs????should i go with the audiobahn? also i am looking at a 2400 watt  concept cc-d2400a is this amp any good?????

Like esmith said you could get 2 jbl 1200.1 amps and they would rock those 15's.  Trust me i own one of the 1200.1 models hooked up to 2 kicker cvr's and it had more than enough power to handle the kickers im scared to turn the amp up.
