EXPERIENCE THE POWER OF MUSIC
Purpose-built for the marine environment, the Signature Series marine amplifiers feature some of the most impressive protection from the environment available — delivering a Signature performance out on the water.
Class-D amplifier design delivers higher efficiency and greater output.
Connect up to two speakers per channel at 2 ohms, or bridge two channels at 4 ohms for increased power.
Conformal coated PCBs provide extra protection from the marine elements.
Rigid aluminum alloy heat sink is molded for greater dissipation of heat.
The amplifiers are available in monoblock, 4 channel, 5 channel, 6 channel and 8 channel configurations.
Engineered to last season after season, the amplifiers include a supported 3-year warranty.
DESIGNED AND ENGINEERED TO TRUE-MARINE™ STANDARDS
Built on the True-Marine design philosophy from Fusion, the Signature Series amplifiers have been tested to a high level of protection against salt fog, temperature, vibration and UV.
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 a whole new level of audio performance.
SUPERIOR SYSTEM PERFORMANCE
The Signature Series amplifiers feature built-in variable bass boost, a subsonic filter and variable low/high pass crossover filters for superior performance and enhanced system protection.
