P600X4

The Rockford Fosgate P600X4 from the Punch Series is a powerful 4-channel amplifier featuring Class A/B technology that impresses with high sound quality, versatile connectivity options, and extensive adjustment features. With a total output of up to 600 watts RMS, this amplifier is ideal for driving high-quality front and rear speakers or a combination of speakers and subwoofers.

Thanks to its bridgeable channels, the P600X4 can be flexibly used in 4-, 3-, or 2-channel mode. The built-in high-pass and low-pass filters allow for precise adjustment to different speaker configurations. With the adjustable Punch EQ2, both the bass and treble ranges can be specifically boosted.

The innovative C.L.E.A.N. system with clip indicators makes it easy to set the input sensitivity correctly and helps prevent signal distortion. High-level inputs with an automatic power-on function also allow connection to many factory-installed car stereos without the need for an additional remote wire.

A solid aluminum heat sink, comprehensive protective circuits, and concealed controls round out the high-quality features.
