Fusion Apollo 4 Channel Marine Amplifier (150W RMS/ch)

The Fusion Apollo MS-AP41200 is a 4-channel Class-D marine amplifier rated at 150 W RMS per channel into 4 ohms (CEA-2006). It is the step up when the built-in amp in a compact stereo like the MS-RA60 is not enough for bigger speakers, a second zone, or a louder cockpit on a bay boat or center console.

Soft-pairs with our Fusion MS-RA60 head unit and the MS-RA60 + EL Classic speaker kit. Use the stereo line outs into the Apollo RCA inputs, keep the AMPLIFIER ON wire tied in so the amp follows the head unit, then finish DSP setup in the Fusion-Link app. Pair with our XS Series 6.5" Classic speakers when you want more clean power to the cockpit.

Channels support a 4 ohm nominal load (2 ohm minimum). Bridged mode with the included high-power adapter is there for a sub or a high-power full-range speaker when you need it.

Good to know
