All-in-one powered subwoofer

The Rockford Fosgate P300-10 combines a 10-inch subwoofer, a 300W RMS amplifier and a sealed enclosure in a single unit. It is designed for drivers who want deeper bass without assembling separate components or running complex wiring.

300W RMS capacity and headroom

The built-in amplifier delivers 300 Watts RMS to the proprietary woofer, with a closed-loop design that matches woofer, amp and enclosure. An adjustable 12dB/Octave low-pass crossover and 0°/180° phase switch let you tune output, while thermal and over-voltage protection prevent damage when pushed hard.

Upgrade from passive subwoofers

This enclosure replaces a passive subwoofer plus external amplifier, saving space and installation time. It is not for systems that already have a dedicated mono amp and custom box, or for installations requiring more than 300W RMS of continuous output.

Questions about this item

Will the 300W RMS amplifier in this P300-10 work with my factory head unit that only has speaker-level outputs?

Yes, the enclosure includes separate low-level and speaker-level inputs so you can connect directly to a factory head unit without a line-output converter.

How can I verify the built-in amplifier is operating correctly once the subwoofer is installed?

The unit is CEA 2006 compliant, meaning its 300W RMS rating is independently verified; the intelligent auto turn-on function activates the amp when a signal is present, and the power LED confirms operation.

Does the box include everything needed to install the P300-10, or must I purchase a wiring kit separately?

The package includes the sealed enclosure with integrated 300W amp, a 10" Punch subwoofer, a detachable power/ground connector, and a remote bass level control; you must supply your own power, ground and signal cables.
