Rockford Fosgate P2D4-8

Engineers at Rockford Fosgate designed the P2D4-8 8" subwoofer to dish out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar® fibers used in bulletproof vests so you get the best of both worlds — warm bass that's exceptionally hard-hitting. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.
