Rockford Fosgate

Regular cab truck owners — Rockford Fosgate feels your pain. They've designed their Punch Stage 3 shallow enclosures so you don't have to suffer without good bass. And they build these boxes for strength and durability, with a computer-optimized design that uses medium-density fiberboard and thick carpeting. The P3L-S12 sealed enclosure measures only 6-5/16" deep at its bottom, so it'll fit in the space behind most regular truck cab seats. It comes preloaded with a single 12" Punch Stage 3 Shallow dual voice coil subwoofer that'll handle up to 400 watts RMS. The enclosure's 4-ohm total impedance means it's compatible with most amplifiers.
