i have 2 kicker l5 10's in my single cab truck i custom built the box to fit. they sound incredible in there but you will have NO room behind your seat for anything else.

 

Well I ended up building a box to go in the middle of the back seat on the ground. It eliminates the use of the cupholders back there but I just made a spot on top of the box that has 3 cupholders in it. The box will be able to hold either one 10" or one 12". I'm probably going to end up goin with the 10". And just my luck I was browsing online and found this box that goes under the rear seat and it was on sale so if any of you were looking here it is.

Where are you guys mounting you amps at? Under the front seats? Is there room under the rear seat with one of those sub boxes that go under the rear seat?
