Marine Class D Amplifier
The Kenwood eXcelon XM802-5 is a five-channel marine amplifier built for boats and powersports vehicles. It delivers 50 watts RMS per channel to four speakers and 300 watts RMS to a subwoofer at four ohms, or 75 watts to four speakers plus 500 watts to a subwoofer at two ohms. Class D circuitry keeps heat low and efficiency high. Conformal coating and sealed terminal caps protect the internals from moisture and corrosion.
Open-water audio builds
This amplifier suits installers who need a single box to drive a full speaker array plus a subwoofer in a wet environment. The one-side connection layout and sliding terminal cover simplify wiring in tight consoles. Buyers who only need two channels or who require a separate mono block for higher subwoofer power should look at a different configuration.
Five-channel power split
The deciding specification is the 500-watt RMS rating on the fifth channel at two ohms combined with 75 watts on each of the four main channels. That power split determines whether the amp can drive your chosen speakers and subwoofer to the volume levels you want. Match the impedance of your subwoofer to the two-ohm rating to access the full 500 watts.

Questions about this item
Do I need a separate head unit or receiver to drive the speaker-level inputs on the XM802-5?
Yes, the included speaker-level harness connects to factory receiver speaker wires, so an existing head unit or receiver is required.
Can the XM802-5 power four speakers and a subwoofer simultaneously using its 50 W and 300 W RMS ratings?
Yes, the five-channel design delivers 50 W RMS × 4 to full-range speakers plus 300 W RMS to a subwoofer at four ohms.
How can I verify the amplifier is operating correctly after installation?
Check that the conformal-coated boards show no corrosion, all protective caps are seated, and the sliding terminal cover is locked in place.
