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.   

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

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.

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.
