Rockford Fosgate P300X2 2-Channel Car Amplifier

The Rockford Fosgate Punch P300X2 is a full-chassis, 2-channel car amplifier designed to add clean, controlled power to a pair of speakers or a compact subwoofer system. It is suited to listeners who need more output and headroom than a factory radio or low-power amplifier can provide. With stereo and bridged operating modes, it can support a focused front-stage upgrade or a single 4-ohm subwoofer application.

In stereo mode, the P300X2 supplies 100 watts RMS per channel at 4 ohms or 150 watts RMS per channel at 2 ohms. This makes it a practical match for appropriately rated coaxial or component speakers. When bridged, it delivers 300 watts RMS to one 4-ohm load for smaller subwoofer systems.

The amplifier uses a Class A/B circuit topology for full-range amplification and covers a 20 Hz to 20 kHz frequency response. Variable high-pass and low-pass Butterworth crossovers help tailor the signal for speakers or subwoofer duty. Its onboard Punch EQ adds adjustable bass enhancement at 45 Hz, while a separate high-frequency tone control provides additional system tuning flexibility.

Installation flexibility is supported by a single RCA input pair that accepts high-level or low-level signals, along with an auto turn-on circuit for high-level integration. A low-level RCA pass-through output can feed another amplifier in an expanded system. C.L.E.A.N. setup support and input/output clip indicators help with gain adjustment.

The P300X2 is built for conventional 12-volt vehicle electrical systems and uses convection cooling through a cast-aluminum heatsink. Its compact 2.38 x 7.76 x 9.86 inch chassis can fit many under-seat, trunk, or cargo-area installations when adequate ventilation is provided. It is a flexible choice for a moderate-power speaker upgrade today with the option to reconfigure for a bridged subwoofer setup later.

Key Features

• 300-Watt RMS Platform: Delivers rated stereo or bridged power for speaker or subwoofer systems.
• 2-Ohm Stereo Capability: Provides up to 150 watts RMS per channel at 2 ohms.
• 4-Ohm Bridged Mode: Supplies 300 watts RMS to one compatible subwoofer load.
• High/Low-Level Inputs: Works with many factory and aftermarket source units.
• Variable Butterworth Crossovers: Helps direct appropriate frequencies to connected speakers or subwoofers.
• C.L.E.A.N. Setup Indicators: Supports more precise gain setting and clip monitoring.

Design & Installation

The P300X2 uses a cast-aluminum heatsink, convection cooling, captive C-clamp power and speaker terminals, and a stealth top-mounted control panel. Protection features include short-circuit and over-current protection, along with power, protect, and thermal status indication. The chassis measures 2.38 x 7.76 x 9.86 inches and has a listed shipping weight of 9.5 pounds.

Use the amplifier in stereo with two 2-ohm or 4-ohm speaker loads, or bridge it only to a 4-ohm load. Rockford Fosgate specifies 4 to 8 AWG power wire, 8 to 18 AWG speaker wire, and a 50-amp external fuse, which is not included. Mount the amplifier securely in a ventilated location, use the selectable crossover mode appropriate to the speakers, and set gain with the C.L.E.A.N. and clip-indicator functions.
