HAC-3000.4D+RWK0CU+RTR172

This bundle combines the Hifonics Colossus Pro HAC-3000.4D four-channel amplifier with a Rockville 0 gauge OFC wiring kit and an extra RTR172 RCA cable, covering the power wiring and the second signal run a 4-channel system needs when front and rear speakers each get their own line. The half-bridge Class D amplifier pushes 3000 watts total, breaking down to 800 watts per channel at 1 ohm, 500 watts at 2 ohms, or 300 watts at 4 ohms, and bridges to two channels at 900 watts each for running a pair of subwoofers instead of four speakers. A variable crossover tunes the high pass from 15Hz to 6kHz and the low pass from 40Hz to 2kHz, and the built-in bass control adds up to 12dB of boost through the included remote. An iron core transformer keeps interference low, and the extruded aluminum heat sink with variable-speed fan cooling handles the heat that comes with this much output. The wiring kit supplies 17 feet of 0 gauge power cable, a matching ground cable, a 17-foot copper RCA pair, 12 gauge speaker wire, and a gold-plated ANL fuse holder rated for 200 amps, and the extra RTR172 cable adds a second RCA run so a front/rear or bi-amp setup doesn't need to split one pair of inputs across two zones.
