I was wondering what subwoofer would fit great in my 07 classic chevy silverado 2500hd crew and still sound awesome? Looking at SSA, FI, Sundown Audio and anymore suggestion would help. I know I need a custom build enclosure for my system to sound awesome while still retaining the rear seat. Hopefully a enclosure builder will chime in letting me know what I can put in this truck. I have a rockford fosgate power series 1000bdcp amp running my two kicker cvr 10s now in the truck.
