With these tough and ultracompact amplifiers, you can enjoy every note from every part of your boat. Features Efficient CLASS-D design Available in monoblock, 4 channel and STAGGERED-POWER 6 channel BUILT-IN Lcd display for manual control Ignition protected and IP67-RATED (excluding cables) Easy tune feature 300-WATT Monoblock Amplifier: This monoblock amplifier is specifically designed to power a subwoofer. 300-WATT 4 Channel Amplifier: This 4 channel amplifier can power up to a maximum of four pairs of speakers or two pairs of speakers and one subwoofer. 600-WATT 6 Channel Amplifier: This staggered-power 6 channel amplifier can power up to a maximum of six pairs of speakers or four pairs of speakers and one subwoofer. Easy Tune Feature: For additional optimization, pair with a Fusion® stereo with built-in DSP, and download the Fusion® Audio app for selectable profiles. This enables the Easy Tune feature, which streamlines amplifier setup to ensure superior sound quality and system protection. CLASS-D Amplifier Technology: The highly efficient Class-D design provides lower battery drain with a higher output than Class-AB amplifiers. This delivers increased power to the connected speakers/subwoofers for an enhanced level of audio performance.
