Take your music to the streets. Boom!™ Audio Amplifier Kits allow you to crank up the volume with significantly less distortion. The amplifier provides more power than Original Equipment radio alone, resulting in increased volume, fuller sound reproduction, reduced clipping and lower Total Harmonic Distortion (THD) than head unit alone. Unlike aftermarket amplifiers that connect between the radio and the speakers, the Boom!™ Audio Amplifier bypasses the internal power amp of the radio to produce the cleanest sound possible. The Boom!™ Audio Amplifier boosts the pure source signal, minimizing any distortion generated through the speaker output. The system-matched high-output signal features optimized sound equalization for crisp, clear vocals and maximum bass response and the strong midrange response cuts through wind and road noise. The waterproof 4-channel, 75 watts/channel amplifier (300 watt total) has been designed from the ground-up for the harsh motorcycle environment. Fairing mounted kit includes all mounting hardware and wiring harness. Dealer Digital Technician software update is required. Dealer installation is recommended. Installation of a third or fourth set of speakers requires the Boom!™ Audio Speaker Expansion Kit, P/N 76000280. Harley-Davidson®. Made in the USA.
- NOTE: Use of a Boom!™ Audio Amplifier turns off the radio's internal amplifier. Installation of a third or fourth set of speakers requires the Boom!™ Audio Speaker Expansion Kit.
