Rockford Fosgate Punch P400X4 4-Channel Amplifier

The Rockford Fosgate Punch P400X4 amplifier delivers 50 watts RMS to both front and rear speakers, providing clean and powerful music even at higher volume levels. Utilize the high-pass filter to increase speaker efficiency by eliminating low bass. Additionally, the amplifier can be switched to 2-channel mode for powering two subwoofers with up to 200 watts RMS each. The built-in low-pass filter allows for optimal sound adjustment for your subwoofer and enclosure combination. Bass and treble boosts are also included through the Punch EQ2, allowing for added depth and brightness to your music.

Setting it up for optimum performance

Rockford Fosgate distinguishes themselves once again with their unique C.L.E.A.N. technology (Calibrated Level Eliminates Audible Noise), a setup system specifically designed for optimal sound quality. By downloading the setup tones and following a few easy steps, this technology ensures that your music will always sound clean and powerful. Simply adjust the receiver volume until the red clip light on the amp goes out, then increase the amp gain until a blue light appears. This straightforward process will perfectly align your amplifier to match your receiver's output, providing maximum power and minimal background noise for an outstanding listening experience at any volume.

Keeps an eye on things while playing

The amplifier's blue light turning solid red indicates that the source is distorting while music is playing, prompting you to lower it to avoid damaging your equipment. The optional PLC2 remote level control also serves as a clip indicator, allowing you to monitor clipping from the front seat. With a built-in computer, the amplifier monitors the output current to protect against potential damage from fluctuating speaker impedances or a short circuit.

Maintaining coolness raises efficiency and lowers distortion

This amplifier features Rockford Fosgate's Dynamic Thermal Management system, which utilizes forced air to evenly distribute heat across the amp and disperse it through the high-mass heatsink. This effectively removes heat from crucial internal components. Additionally, the proprietary MEHSA cooling process ensures optimal heat transfer from the MOSFET devices to the heatsink, allowing for efficient dissipation and ensuring cooler and more effective transistor performance.
