I have:
Pioneer DEH-P6000 deck
Directed 600d amp (600 watts)
3 JL 10" W3 subs
and sitting in my room is 2 JL 12" w0 subs
I'm suprised nobody else so far has any JL subs. I've got a few of my friends to switch from other brands(pioneer, fosgate, mtx) to JL after listening to my system. At least see what they have to offer --->
