Marine MA704 4-Channel Marine Amplifier

If you've ever tried to power your boat's speakers with a marine radio, then you know that you need serious power to get good sound out on the open water. Sporting a sleek stealthy profile, JBL's MA704 marine amplifier will deliver 70 watts RMS each of four separate speakers. The amp could also power two speakers and a sub, in 3-channel mode. For even louder fun, you could bridge the amp to 2-channel mode and power a couple high-performance speakers with 200 watts RMS each. And JBL uses a coated circuit board and stainless steel connectors to ensure that this amp will rock for many seasons to come.

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 and subs.
