HAC-2000.4D 2000w 4-Channel Amplifier Class D Car Stereo Amp + Wire Kit

This bundle brings together the Hifonics Colossus Pro HAC-2000.4D four-channel amplifier, a Rockville RWK01 0 gauge wiring kit, and an extra Rockville RTR172 17-foot RCA cable, covering both the power delivery and the second set of RCA runs a 4-channel install typically needs for front and rear speakers. The amplifier's half-bridge Class D design pushes 2000 watts total, breaking down to 500 watts per channel at 1 ohm, 300 watts at 2 ohms, or 175 watts at 4 ohms, and it bridges down to two channels at 750 watts each for powering 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 manages heat during longer listening sessions. The RWK01 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, while the extra RTR172 cable adds a second color-coded RCA run so front and rear channels can each get their own dedicated signal line instead of splitting one pair. Together, the three pieces cover the full wiring needs of a 4-channel amplifier install.
