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.
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.
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.
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.
Helping to extend the life of your amplifiers, the Signature Series amplifiers are designed with conformal coated PCBs to provide extra protection from the marine elements.
For increased efficiency, the rigid aluminum alloy heat sink is molded to form a singular die-cast chassis. The fin layout is calculated with precision to increase the surface area of the heat sink and improve heat dissipation.
The polished stainless steel control panel cover conceals and helps protect all cable connections and settings controls while providing an attractive finish to complement any installation.
The Signature Series 2250-watt monoblock amplifier is specifically designed to power a subwoofer. The amplifier is configurable for 1-ohm impedance for extra power.
The Signature Series 1,400-watt 4-channel amplifier can power up to a maximum of four pairs of speakers or two pairs of speakers and one subwoofer.
The Signature Series 1600-watt 5 channel amplifier can power up to a maximum of four pairs of speakers and one subwoofer.
The Signature Series 1500-watt 6 channel amplifier can power up to a maximum of six pairs of speakers or four pairs of speakers and one subwoofer.
The Signature Series 2000-watt 8 channel amplifier can power up to a maximum of eight pairs of speakers or four pairs of speakers and two subwoofers.
Designed for boats operating on 24-volt electrical systems, the Signature Series 24-volt 6 channel amplifier can power up to a maximum of six pairs of speakers or four pairs of speakers and one subwoofer.
