well im insterested theres a few subs and amps im looking for to buy to put into my gf's car, ive always wanted to do a 15, but if i ge a 12 i can use it in my truck also...but then again i dont think ill ever wanna pull my aq out of it, its over 100 pounds with the box in a reg cab truck so its not fun, but ill talk to her, she only wants to use half of the truck so i dunno if she wants to do a 15, i still need to take measurements
