Boss Audio Elite MPD380.4 4 Channel Class D Marine Amplifier, 380W, IP66, 2 Ohm Stable

The Boss Audio Elite MPD380.4 is a Class D marine amplifier with a 380-watt high output rating and an IP66 enclosure that guards against dust and weather. It can run in four-, three- or two-channel configurations and is bridgeable, which lets one amplifier cover a range of speaker layouts on a boat. The design is stable down to 2 ohms and relies on a PWM MOSFET power supply.

Tuning is handled with high-pass and low-pass filters, bass boost and an input sensitivity adjustment, and the amplifier accepts low-level RCA signals from a stereo. LED lighting on the end panels makes the unit easy to spot in dim compartments, and built-in thermal, short and overload protection circuits help safeguard it in use. Its footprint of 9.76 by 5.12 by 1.97 inches helps where mounting space is limited.
