HAC-1500.1D 1500w Mono Amplifier 1 Ohm Class D Car Audio Amp + Wire Kit

This bundle pairs the Hifonics Colossus Pro HAC-1500.1D mono amplifier with a Rockville RWK21 2 gauge wiring kit, so the power, ground, RCA, speaker, and remote cables needed for a clean subwoofer install are already accounted for before you start. The amplifier uses a half-bridge Class D design with fewer internal components than a traditional layout, which lets it push 1500 watts at 1 ohm, 750 watts at 2 ohms, or 375 watts at 4 ohms depending on how the subwoofer load is wired. A variable electronic crossover with a 15Hz to 1kHz high pass and a 50Hz to 10kHz low pass, both adjustable in 12dB per octave steps, lets you tune the amp to the subwoofer instead of running it wide open, and the built-in bass control adds up to 12dB of boost from the included remote. An iron core transformer keeps electromagnetic interference low so the amp doesn't talk to other electronics in the vehicle, while a variable-speed fan paired with an extruded aluminum heat sink manages heat during extended bass-heavy playback. The included RWK21 kit brings 17 feet of 2 gauge power cable, 17 feet of true 100% copper twisted-pair RCA cable, a 17-foot remote wire, 14 gauge speaker wire, a 3-foot ground cable, and a gold-plated ANL fuse holder with a 150 amp fuse, plus the terminals and split loom needed to route everything cleanly. Buying the amp and the wiring together means the whole subwoofer circuit, not just the amplifier, is ready to install in one afternoon.
