Rockford Fosgate P3S 8" shallow mount subwoofer delivers “Punch” even when depth is limited. The P3SD4-8 features Dual 4-Ohm voice coils for wiring flexibility and 150 Watts RMS power handling.
The Rockford Fosgate P3S 8" shallow mount subwoofer delivers Punch, even in depth limited situations. Rockford Fosgate understands all vehicles are not the same, because some cannot accommodate deep subwoofers. In the past, that meant no Bass. Not anymore! Now even depth challenged vehicles can have REAL Bass and the Dual Voice Coil allow configurations for every application. Shallow woofers are specifically designed for spaces where a traditional woofer cannot be used.
