Show original supplier description
The Rockford Fosgate Punch P600X4 is a versatile 4-channel amplifier designed to power various audio system configurations. It delivers 75 Watts RMS x 4 channels at 4-Ohm, or 150 Watts RMS x 4 channels at 2-Ohm. For higher output, it can be bridged to produce 300 Watts RMS x 2 channels at 4-Ohm. This amplifier features a Class A/B topology for efficient and reliable performance. It includes a variable high-pass/low-pass crossover (50Hz-250Hz at 12dB/octave Butterworth) and built-in Punch EQ for precise tuning of bass frequencies, offering up to +18dB boost at 45Hz. It also supports high-level inputs with an Auto Turn-On circuit and has RCA pass-thru outputs to minimize the need for Y-adapters as your system expands. Key technologies include Rockford Fosgate's C.L.E.A.N. Set-up with in/out clip LEDs for system matching, NOMAD for protection against short circuits and low impedances, and Dynamic Thermal Management (DTM) for even heat distribution. The amplifier is CTA-2006 compliant, ensuring its power ratings are real and not inflated marketing figures. It requires 4 AWG power wire and 8 AWG to 18 AWG speaker wire. Specifications include a frequency response of 20Hz to 20kHz +/- 1.0dB, a THD+N of less than 1.0% at both 4-Ohm and 2-Ohm, and an average efficiency of 68% @ 4-Ohm. The dimensions are 2.38" x 7.76" x 13.28".
