what to do with 9 cubes (gross)

[CPT.scratchandsniff]

I haven't been on in a while and am looking for inspiration. i want to replace the single 10" kicker L7 in my reg-cab pickup with something bigger... im going to ro-do my seat frames and put an aluminum fuel tank in the bed so i can flatten out the side saddle tank humps in my floor. my rough measurements say i should have just over 9 cu.ft under/between the seats while maintaining full width behind the seats for my amps.

my question is what to do with 9 cubic feet... single 18, pair of 15s? 4 10's? power and budget aside (be reasonable) what wouldyou do with 9 cubes?

Pair of 15's

Pair of 12s with a slot port.

if i had 9 cubes to play with id try 2 15's ported or an 18" bandpass just my 2 cents

If it's 9 ft3 just for the box, I would do an 18" sub, or 2 15"s the if budget is bigger.

If you still need room for batteries and amps, maybe 2 12"s can fit.
