Fusion Apollo marine amplifiers are the difference between hearing the music and feeling it. These amplifiers are efficient, easy-to-install and designed exclusively for use with compatible Fusion DSP-enabled stereos (Apollo RA770, Apollo RA670, Apollo WB670 and RA210) and Fusion speakers. The 8 channel amplifier is designed to power up to eight pairs of speakers or four pairs of speakers and two subwoofers with its 2400-watts peak power (150-watt RMS per channel) and features the Easy Tune feature to automatically regulate audio settings for the best sound quality without manual adjustments (requires setup using the Fusion-Link app on a compatible smartphone).
