ok i know you dont want to hear this but you dont want an l7. they are very unreliable and they dont sound good at all. if you want loud and you want to replace them often go for it. but if not your better off with something else. where are you located there are a few dealers on here that would be able to help you.
im in northern indiana...i just wanted some fairly cheap subs that would bump nice, ive gotta really small car an eagle talon so it doesnt take much to get loud in there, any suggestions for subs and an amp to power them and prices?
if you are going with the L7s and they are dual 4ohm id get a hifonics bx1605d on them and get a good box for them. but like bill said there are better out there.
