They would need more than 2.5 each, right?

kicker specs 3 cu/ft, but with the constrants given, thats the best you can get.

now if you give another 10 inches in in any direction, then there are hundreds of options.

or of course loose a driver somewhere... actually, with the amount of space given the system would probally preform alot better with 3 drivers then 4 at the same power.

i would say 15cuft net tuned to 30Hz and no less then 112 sqin of port area. i would go a little bigger. it would be loud and you would still get a very strong low end bass.

I wouldn't recommend putting the speakers on different planes. Rather, I would make a CRX style box and have the four speakers on top.

why would it make a diffrence? cancellation?

I agree, but in this case that type of box would either be 33x33x22 or 8 cu/ft and thats even worst then the previous design.

When it comes down to it to fit the same requirements its probally better to use less drivers.

I think of it this way. If I can build a 10.5 cu/ft box with the specs given and use 2 drivers both in an ideal condition why not, then all you would have to do is cutt 2 more holes if you not happy.

Ideally, you don't want the speakers firing directly into each other. You get cancellation issues pretty bad.

Yes I know, I'm just saying though. It's not like he gave us any dimensions anyway lol :rolleyes:

Internally, that can be solved.If you were commenting about externally, you must not look at any SPL installs that maximize which way the vehicle likes subs/ports placed.
