Built for the ElementsYour normal car audio components can't take the abuse of the Marine environment for long. The elements like water, salt/fog, and the blazing sun can cause your system to quickly breakdown in a short period of time. Because of this, Alpine has engineered the PDX-5M to withstand the harsh Marine environment. The PDX-5M has undergone rigorous ATSM-B117 testing for salt/fog to help prevent corrosion. The outside case passes the ASTM-G154/D4329 accelerated weather test for superior UV protection to prevent sun damage. All this attention to detail will provide the best sound experience and reliable performance on the water for your boat season after season.
System Building Made EasyWant to build a basic system for your boat to start out? Do you have limited space but still want dynamic sound? Then the best amp to start with is the PDX-5M. With this one amp, you can connect four speakers and a subwoofer for outstanding sound quality. The amp provides 75 watts RMS to four channels and an incredible 300 watts RMS to a subwoofer. You get everything you need to power a complete system with the PDX-5M for loud and clean sound while you are cruising on the open water.
Accurate Dynamic Sound ReproductionAlpine's goal is to deliver the best sound quality possible. With the PDX-5M, digital switch-mode amplification yields incredible sound quality. Advances in the PDX design include improved feedback circuitry to faithfully reproduce the input signal for improved dynamic range and higher fidelity. If you are listening to your favorite rock song, your amp is ready to jump from loud to calm and back again with ease.
