The big power your boat's system needs

If you've ever tried to power your boat's speakers with a marine radio, then you know that you need some serious power to get good sound out on the open water. Sporting a stylishly sleek profile, JBL's Marine A1504 amplifier will deliver 150 watts RMS to each of four separate high-performance speakers or component sets so your music will play loudly and clearly everywhere throughout your boat, fore and aft.

High-power applications

For maximum fun, you can bridge the amp to 2-channel mode and power a pair of high-performance speakers or subwoofers with 450 watts RMS each. You can also use this amp to power two speakers and a subwoofer in 3-channel mode, with 150 watts going to each of your full-range speakers and up to 450 watts going to the sub.

Works with almost any system

High- and low-pass filters help the amp to clarify and maximize the performance of your speakers and subs. Speaker-level inputs allow this amplifier to work in almost any system, even if you're keeping your boat's original radio. JBL includes the right adapters to make these high-level connections. They also build the amp with coated circuit boards and stainless steel connectors to ensure that this amp will rock on the water for many seasons to come.
