Rockford Fosgate T1000-4AD Power 1,000 Watt Class-AD Full-Range 4-Channel Amplifier

The T1000-4ad combines sound quality characteristics of Class-A designs with efficiency of a Class-D in one remarkable package. Superior sound quality is possible through the implementation dynamic switching frequency control. The addition of Constant Power circuitry produces optimized output at a range of impedances. Rockford Fosgate created Class-bd for brute power to run low frequency subwoofers, and now Class-ad offers high fidelity in a full-range configuration. 2/4 channel input switch 24dB/octave crossover 4 Gauge power/ground connectors Audiophile grade speaker connections MOSFET power supply MOSFET output stage RCA pass-thru outputs.
