T600-4

The Rockford Fosgate T600-4 from the high-performance POWER series is a premium 4-channel Class AB amplifier that impresses with its powerful output, precise sound reproduction, and extensive customization options. With a total of 600 watts RMS at 2 ohms, this amplifier is ideal for high-end car audio systems and for powerfully driving speakers or subwoofers.

Thanks to the built-in Punch EQ tone control, the bass and treble ranges can be adjusted individually. The variable high-pass and low-pass filters allow for precise tuning to different speaker configurations. Dynamic Thermal Management ensures efficient heat dissipation, while the built-in NOMAD protection circuit safeguards the amplifier against overloads and short circuits.

The T600-4 also features balanced inputs, high-quality MOSFET technology, and a high damping factor for controlled, dynamic music playback.
