When it comes to buying audio equipment for your boat, you need gear that's tough enough to withstand abuse from the waves, the sun, and whatever else the weather may bring. Sony's XM-604M 4-channel marine amplifier handles all that with flying colors so you can enjoy great music out on the water.
The XM-604M features a special coating that protects the circuit board against damage from mold, mildew, and moisture, while gold-plating helps the RCA connectors resist corrosion. You can expect long-term durability from this well-tested design.
The highly efficient power supply ensures that you get stable, regulated output power for clear, unmuddled sound. The built-in high- and low-pass filters direct different frequencies to the appropriate speakers for maximum system efficiency. If you're using the speaker-level inputs, the amplifier powers up automatically when it senses a signal so you don't have to run a separate turn-on wire. You can bridge the amplifier's rear channels, turning it into a 3-channel amp.
