ive been struggling for a week now trying to figure out what to do with my four 12s.....i also love the look of subs in the spare tire well..but....alas, tis not enough space! thought about putting one 12 in the well, then 3 going around.. but that'd be a pain too..so ive decided to just make a box for all 4, 2 ported, 2 sealed, the ported speakers facing up, with the ports aiming to the front, on the bottom, then the 2 sealed in the back, on an angle facing the hatch..hopefully i'll have this done tomorrow or the next day..just need to port the current box, and add on a bit for the sealed part..
tho maybe if you're interested, ill trade ya my four audiobahn 12s for your two 15s...depending on what kinda 15s they are
hehe
