HCM-800.4D 800w 4-Channel Car Amplifier Class D Compact Amp + Wire Kit

This bundle pairs the Hifonics Colossus Mini HCM-800.4D four-channel amplifier with a Rockville RWK42 4 gauge wiring kit, stepping up the power of the compact 4-channel Mini lineup while keeping a footprint that fits motorcycles, UTVs, and tighter cabin installs. A mass-loaded extruded aluminum heat sink cools the amp without a fan, and it pushes 800 watts total, breaking down to 200 watts per channel at 2 ohms or 100 watts at 4 ohms, and bridges to two channels at 400 watts each for a pair of components. Nickel-plated RCA inputs resist corrosion, and a delayed turn-on function keeps the amp from adding pops or hisses when the source unit powers on. Speaker-level inputs let it run without RCA outputs from the source unit, useful for factory head unit installs. The RWK42 kit supplies two sets of copper RCA cable for the 4-channel setup, 17 feet of 4 gauge power cable, 16 gauge speaker wire, an 18 gauge remote wire, and two AGU fuse holders with 100 and 60 amp fuses, along with the terminals and split loom needed for a clean install. Together, the amp and kit cover a full 4-channel speaker upgrade at nearly double the power of the smaller HCM-400.4D bundle.
