I would like some opinions.Getting jumpy on building a box for the back of an 87 supra I did some math and figure I got about 4.5 to 5 cubic feet with a box size that would fit just about right without many problems.my question is what would give me more punch inside the car.don't really care about outside the car.box would be ported and would be powered by a decent 2000-2500 watt amp not sure on which one but got it narrowed down.I wouldn't mind inverting subs either if need be for 4 tens.subs would be matched to the amp give or take a few rms.thanks ahead for any ideas.
