2001 330i, i guess i will be doing some fiberglassing. use up all that spair tire well. i already got the subs and amp. if you can give me an idea of the smallest bandpass you can do with 2 15s.
1-1.25 each sealed chamber for the 15s

then 2.5 bandpass chamber

dont do it...u will have a bandpass that will sound like a high powered midbass

u will not have much if any low end..unless u add an epicenter to restore the lost bass

80 inch what are you running in your avitar. if you where to cut it down to 2 subs it doesnt look like that box is huge

thats a old box for my friends escalade ext

6 jlw7's in a 4th order and that box was huge...9cubes sealed (1.5 cubes per sub)

playing into 15cubes ported with 256 square inch port

I got 2 12s in a sealed in my 328i 15s I dont see it as a possibility. You should trade the 15s for some 12s and go from there but then again wtf do I know
