Power delivered in style

Do you want to bring the party on board? Infinity's handsome M4555A marine amplifier will add plenty of muscle to your music, sending 45 watts RMS to each of four speakers, while delivering up to 500 watts RMS to a subwoofer. For a high-performance system, you can bridge the amp to 3-channel mode to power two speakers with 130 watts RMS each, while still driving a sub with 500 watts. The amp features a coated circuit board and stainless-steel connectors that will stand up to the sun, salt, and spray.

Works with almost any system

Speaker-level inputs allow this amplifier to work in almost any system, even if you're keeping your boat's original radio. The separate high- and low-pass filters on the front and rear channels help maximize the performance of your speakers. The low-pass filter, bass boost, and phase switch on the sub channel lets you custom tailor the sound of your bass.
