The Power T600-4 is a 4-channel amplifier capable of producing 150 Watts into each of its four channels at 2-Ohms. The T600-4 can run a 4-way full-range system or use component speakers on the front with subwoofers on the rear.

The T600-4 amplifier offers the perfect balance of power output and compact design required for high performance audio systems. The 4-channel configuration allows fine tuning adjustments between front stage component systems and rear surround speakers. The built-in crossover also allows the rear channels to be configured for running one or two subwoofers.

CTA-2006 Compliant

Power ratings on Rockford Fosgate amplifiers conform to CTA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.


DSM (Discrete Surface Mounted Components) utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.


Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.


MEHSA³ reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.


NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.

Punch EQ2

Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.


Trans•ana is a Class A/B topology that simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality.


Rockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.
