How many 10's behind seat.....
 

Can you fit 4 10's behind the back seat of an 02 supercrew? Or would 3 10's be better? I like JL subs, so I'll probably get either the 10w3's or the 10w0's. Can an amp be hooked up to the factory in-dash 6cd head unit?

hmmm, now that I look around im not so set on JL subs. Does anyone have any suggestions for good 10in subs? I like the infinity reference subs.

Also I have (4) MTX 6000 12in subs sitting in my garage if anyone wants them I will sell or trade them.

the infinity reference subs are really nice. i had a pair of the i r 1020's in a sealed box and they would pound and they are really good sound quality subs. i think crutchfield is having a sale on them right now. i was powering them with an alpine mrd 300 for the pair. good luck.
