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 compatible stereo with built-in DSP, and download the Garmin 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.
RUGGED DESIGN
These amplifiers offer superior levels of durability and are built to IP67 standards (excluding cables) to withstand abuse in harsh marine environments.
