Alpine's goal is to deliver the best sound quality possible. With the Marine PDX series, 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're listening to your favorite rock song, your amp is ready to jump from loud to calm and back again with ease. Play it longer with the engine off!The PDX amplifiers' unique design allow for a clean, easy, and fast install. All the controls and wiring connections are in one convenient location.PDX amplifiers are 60% smaller than previous models with the same output power. Install your amps easily without sacrificing valuable room, power and performance.The PDX amplifiers feature a smart stackable design. PDX amplifiers' exclusive design allows them to be stacked vertically on top of one another. This is an industry-first installation option that saves a ton of space.PDX amplifiers deliver outstanding sound quality. The revolutionary design of the PDX incorporates improved feedback circuitry and power supply filtering system, plus a damping factor that is 350% better than Class A/B amps.A combination of an advanced power supply, Class-D design, and switch-mode digital amplification allow PDX amplifiers to stay extremely efficient at all power levels. This produces less heat, eliminating the need for large heat sinks, just another reason why they can be much more compact than conventional amps.The PDX amplifiers use Direct FETs device to make switch-mode digital possible. Direct FETs are very small output devices that take up less room and they switch on and off extremely fast when needed. Their ultra high-speed switching capabilities allow them to perform at frequencies that other Class-D amplifiers struggle to reproduce. This provides control over power consumption, and cooler operation.
