Space-age power

Looking for one amp to power your boat's sound system? Sporting a sleek stealthy profile, JBL's MA4505 marine amplifier will deliver 45 watts RMS each to 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. And JBL uses a coated circuit board and stainless steel connectors to ensure that this amp will rock for many seasons to come.

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 both pairs of channels help maximize the performance of your speakers and subs. The sub channel features a low-pass filter, bass boost, and phase switch so you can tune your bass the way you want.
