Rockford Fosgate T400X4AD Compact Efficient 4 Channel Amplifier for Car, Motorcycle, Vehicle Sound Systems with 400 Watts of Power

Upgrade your car’s sound system with the Rockford Fosgate 4 Channel Amplifier.

The energy-efficient amplifier is incredibly efficient, making it a great option for hybrid cars, electric vehicles, small cars, trucks, motorcycles, and side-by-side UTVs. This ultra-compact, 400-watt amplifier features Rockford Fosgate’s proprietary Class-AD technology, including Constant Power. Constant Power produces the same output at 4-Ohm and 2-Ohm impedances. Constant Power also gives you 25 percent more output power because it balances demand vs. draw.

The 4-channel amplifier comes with flexible vehicle integration. The configurable input harness with Molex style connectivity accepts RCA and speaker level signals. Top-mounted controls give you easy access to the built-in crossover and C.L.E.A.N. input/output clip detection circuits and Rockford Fosgate’s patented Punch EQ.

Don’t worry about the amplifier overheating. The 3-stage thermal lock extrusion and dual fan forced inductions keep the amplifier cool, while the real-time thermal/protection schemes help safeguard the amplifier.

Install the Rockford Fosgate 4-Channel Amplifier to get the best performance from your car’s speakers and sound system.
