About the Rockford Fosgate PBR400X4D

The Rockford Fosgate Punch PBR400X4D is a 4-channel, full-range Class-D amplifier rated at 400 watts total. It is designed for compact systems and stereo front/rear setups that have little space, such as UTVs, motorcycles, recreational vehicles and hybrid-electric vehicles. Its efficient design draws little current from the electrical system.

It uses Boosted Rail Technology (BRT) to produce its 400 watts. A variable hi-level DC offset turn-on circuit is meant for installation into OEM systems. The amp has differential inputs with high-level auto turn-on and a remote-out feature when using high-level inputs.

Construction includes an extruded aluminum heatsink and discrete surface mount technology. C.L.E.A.N. clip detection with indicator LEDs, real-time output and power supply thermal sensing, muted turn-on and proprietary protection are included. It is CEA-2006 and CE compliant and carries a 1-year warranty.
