Garmin Fusion AM Series Marine Amplifier, 500-watt 4 Channel, A Garmin Brand;

Feature overview: 2 ohm stable mosfet amplifier design. Variable bass boost 0 - + 18DB. Variable lp and HP electronics x-over at 18DB/octave. 4 gauge power and ground connections. Nickel plated audio input and output RCA connections. Nickel plated RCA output for multi-amp installations. 2-Ohm stable stereo. Provides the option of connecting an extra pair of speakers in parallel, 2 per channel at 2-ohms (a total of 8 speakers). marine grade connections nickel plated RCA connectors and stainless components improve signal flow for optimum output. Class-ab design the 500 Watt 2-ohm stable (per channel) design ensures clean and powerful amplification of the input signal, enough to rock the boat. Conformal coated circuitry provides added protection from salt air and moisture to ensure maximum product life. Marine grade chassis stainless steel end and bottom plates provide a stunning finish coupled with environmental protection. Rca line out a pass through RCA output enables linking of multiple amplifiers for enhanced system performance. 2 channels capable of powering 2 speakers, a sub (bridged) or 4 speakers in parallel.
