Alloy Class D Mono Amplifier

The Harmony Audio HA-A800.1 is a Class D mono amplifier from the Alloy series, engineered for maximum power output and efficiency. It delivers a robust 800 Watts RMS x 1 at 1 Ohm and 600 Watts RMS x 1 at 2 Ohms, with peak power ratings of 1600W and 1200W respectively. Its Class D circuitry ensures high power efficiency while keeping the amplifier cool. Installation is simplified with the included HA-EASY adapter, which allows for splicing into factory speaker wires to acquire the audio signal and can also provide the amplifier's turn-on signal via DC offset, eliminating the need for a traditional 12V remote turn-on lead in many cases. For those with aftermarket head units featuring RCA outputs, direct connection is also supported. The amplifier offers selectable input types (high or low level) and adjustable sensitivity ranges, along with comprehensive user-adjustable settings including gain, low-pass filter, subsonic filter, and bass boost (0-12dB @ 50Hz). The HA-A800.1 comes with a remote bass control knob, allowing for easy adjustment of bass levels from the driver's seat. This knob features a 0 to 12 dB boost range and a blue LED indicator. An innovative feature is the daisy-chaining capability: when the amplifier is turned on via DC offset, the empty remote terminal outputs a 12V switched signal, capable of turning on a second amplifier or other 12V accessories (rated at 1 amp maximum). Key specifications include a frequency response of 10Hz-180Hz, a signal-to-noise ratio of 95dB (A-weighted), and full pass-through audio output via RCA connections. The amplifier's dimensions are 12-3/8" L x 6-1/8" W x 2" H. It requires a recommended 1/0 gauge power wiring and a 100A external fuse. This amplifier is presented as compatible with specific Kicker subwoofer box systems for 2004-2008 Ford F-150 Extended/Super Cab trucks, 2002-2018 Dodge Ram Quad/Crew, 1999-2006 Chevy Silverado Extended Trucks, and 2009-2020 Ford F-150 Super Crew trucks.
