Rockford Fosgate P3SD4-8 Dual 4ohm 8” shallow subwoofer

Rockford's bass pedigree
Rockford Fosgate's Punch Stage 3 subwoofers come from a long line of high-performance subs that deliver real deal bass. Now, shallow-mount Punch Stage 3 subwoofers make it easier to get impressive low end in smaller or hard-to-fit vehicles.

Advanced engineering
The P3SD4-8 8" shallow subwoofer hangs with its bigger brethren, thanks to advanced materials and engineering. Rockford uses anodized aluminum for the cone and dust cap making the woofer light and easier to drive, yet rigid enough to maintain its shape under maximum load. The M-Roll Santoprene™ surround also provides excellent excursion for maximum output while being durable enough to last.

Powerful bass for a tight space
A low-profile frame houses the subwoofer, with abundant venting to battle overheating and thermal breakdown. At 2-5/8 inches deep, this sub will fit into places where no bass has gone before — just build a custom enclosure or find a suitable box. The dual 4-ohm voice coils allow you to wire up multiple subs or to coax optimum performance from your amplifier.
