Rockford Fosgate P300-10T 10" Powered Truck Subwoofer

The Rockford Fosgate Punch P300-10T is a self-contained powered subwoofer enclosure designed to add low-frequency output without separately matching an amplifier, woofer, and box. It combines a 10-inch subwoofer, a 300-watt RMS Class-D amplifier, and a sealed truck-style enclosure in one package. It is intended for vehicle systems that need added bass while keeping installation space manageable.

This enclosure is suited to trucks and other vehicles where available cargo space is limited. Its wedge-shaped cabinet uses a shallow 4.8-inch top depth and a 7.9-inch bottom depth to help it fit in tighter locations. The sealed design emphasizes controlled bass integration for daily listening systems.

The P300-10T is built to work with either factory-installed or aftermarket audio systems. High-level speaker inputs support connection to many factory radios, while low-level RCA inputs support aftermarket source units. An input-level selector helps match the selected connection method.

Its integrated amplifier includes a variable low-pass crossover, adjustable Punch Bass EQ, and a 0°/180° phase switch. These controls help blend the enclosure with the vehicle's full-range speakers and accommodate different mounting locations. A wired Remote Punch Level Control lets the listener adjust subwoofer output from the front of the vehicle.

The enclosure also offers selectable automatic turn-on methods for practical integration. It can use a conventional remote trigger, DC-offset sensing, or audio sensing depending on the vehicle and source unit. A quick-disconnect power connector and removable signal harness simplify removal when cargo space is needed.

Design & Installation

The P300-10T uses a sealed, truck-style wedge enclosure constructed from 5/8-inch MDF and covered in heat-activated vinyl. Its cabinet measures 13.3 inches high by 21.7 inches wide, with 4.8-inch and 7.9-inch wedge depths. A metal-mesh grille helps protect the subwoofer, while the enclosure's compact shape is intended for space-conscious vehicle installations.

Installation requires properly fused battery power, a short chassis ground, and either RCA or speaker-level signal wiring. The supplied harness supports low-level RCA or high-level speaker connections, and the auto turn-on selector offers remote-trigger, DC-offset, and audio-sensing modes. Measure the intended mounting area before purchase, secure the enclosure against movement, and set gain, crossover, bass boost, and phase after installation.
