got a L7 12 that ive had for acouple years... its in my 03 dodge now but was in a big ole box in my 98 dodge before i traded it in... i had to make a make shift box for it to fit and i think it just has alot more potential cause i dont have enough room for it... they do make dual 10in sub boxes for my truck so im going to go with that... so i wanna trade for either a sub box for a 03 dodge ram or 10's... and not frickin walmart subs...
