Description

Rockford Fosgate P300-12 Punch 12" 300W Amplified Subwoofer One Box. All the Bass.

Product Overview

The Rockford Fosgate P300-12 is a complete all-in-one amplified subwoofer system, housing a proprietary Punch 12" high-output woofer, a 300 Watt internal amplifier, and a custom sealed enclosure in a single self-contained unit. Designed for straightforward bass upgrades to factory systems and space-conscious installs, the P300-12 requires only a power feed, ground, and audio signal to get running no separate amplifier, no separate enclosure, and no complex integration.

The closed-loop design ensures the woofer, amplifier, and enclosure are engineered and tuned to work together as a matched system, delivering consistent, optimised performance straight out of the box. A built-in adjustable bass boost EQ, 12 dB/octave adjustable low-pass crossover, 0°/180° phase switch, intelligent auto turn-on, and an included remote bass level control give you full system management without additional processors or controllers. Constructed from 5/8" MDF and finished in industrial heat-activated vinyl, the P300-12 is built to handle the knocks and scrapes of daily boot, cargo area, and under-seat use in Australian vehicles.

Features & Benefits

All-in-one amplified subwoofer system: Woofer, amplifier, and sealed enclosure in a single unit. Eliminates the need for a separate amplifier, separate enclosure, and separate wiring runs between components. Ideal for factory system upgrades, rental vehicles, and space-restricted installs in Australian hatchbacks, SUVs, and utes.
300W internal amplifier with closed-loop design: The amplifier is matched and tuned to the specific woofer and enclosure by Rockford Fosgate engineers, ensuring the system performs at its optimum without the guesswork of matching separate components. A closed-loop system consistently outperforms a same-wattage mix-and-match setup.
Proprietary high-output Punch woofer: The 12" driver is purpose-designed for this specific sealed enclosure and power level, delivering the punchy, controlled bass response the Punch series is known for across a wide range of music genres.
Adjustable 12 dB/octave low-pass crossover: Set the crossover point to match your existing speaker system, ensuring the subwoofer handles only the frequencies it is designed for and integrates cleanly with your mid and full-range speakers.
Built-in adjustable bass boost EQ: Dial in additional low-frequency emphasis to suit personal preference or music genre without an external equaliser. Particularly useful for open-air or acoustically challenging vehicle environments.
0°/180° phase switch: Align the subwoofer's output phase with your existing speakers for coherent, integrated bass reproduction essential when the subwoofer is mounted in a different location to the main speakers.
Separate low-level (RCA) and speaker-level inputs: Connects to aftermarket head units via RCA or directly to factory speaker outputs via speaker-level inputs. No head unit replacement required for factory system integration.
Intelligent auto turn-on/off: Senses the audio signal and powers up and down automatically. No remote turn-on wire required, simplifying installation in factory and OEM audio systems common in Australian vehicles.
Remote bass level control included: Adjust bass output from the driver's seat without accessing the subwoofer unit itself. The remote control is included in the box no additional purchase needed.
Thermal and over/under voltage protection: Built-in protection circuits monitor operating temperature and supply voltage, shutting the system down safely before damage occurs. Adds long-term reliability in hot Australian conditions where boot and cargo temperatures can spike significantly.
Detachable power/ground connector: Simplifies installation and removal. Practical for vehicles where the subwoofer may need to be temporarily removed or transferred between vehicles.
5/8" MDF construction with industrial heat-activated vinyl: Rigid enclosure walls minimise flex and resonance at high output levels. The heat-activated vinyl finish is more durable and scratch-resistant than standard carpet, better suited to daily cargo area use.
High-efficiency, low current design: Draws less current from the vehicle's electrical system than equivalent traditional amplifier and subwoofer combinations, reducing strain on factory alternators and wiring important for Australian vehicles without upgraded electrical systems.

Frequently Asked Questions

Do I need a separate amplifier to run the P300-12? No. The P300-12 has a 300W amplifier built directly into the enclosure. You only need to connect a power feed, ground, and an audio signal from your head unit or factory system to get it running.

Can the P300-12 connect to a factory head unit without RCA outputs? Yes. The P300-12 features both low-level RCA inputs and speaker-level inputs, allowing direct connection to factory head unit speaker outputs without requiring an aftermarket head unit or line output converter.

Is a remote bass control included with the P300-12? Yes. A remote bass level control is included in the box, allowing driver's seat adjustment of bass output without accessing the subwoofer unit itself no additional purchase required.

What is the advantage of the closed-loop design? The closed-loop design means the woofer, amplifier, and enclosure are engineered as a matched system by Rockford Fosgate. This ensures the amplifier's output characteristics are optimised for the specific driver and enclosure volume, delivering more consistent and accurate bass performance than a mix-and-match separate component setup.

Is the P300-12 suitable for daily boot and cargo area use in Australian conditions? Yes. The industrial heat-activated vinyl finish resists scrapes and bumps, the MDF construction minimises resonance, and the built-in thermal and over/under voltage protection safeguards the system against the high boot temperatures common in Australian vehicles during summer.
