Alpine PDX-1.600M Marine Mono Subwoofer Amplifier(ALPPDX1.600M) and other affordable Car Amplifiers at 6ave.com.

The PDX-1.600 mono amplifier supplies a whopping 600 watts of power from its amazingly compact body, plenty of punch for most sub systems. Beefy internal components and clever engineering keep the power output strong and the noise low for superb fidelity and control. The adjustable low-pass filter tailors the amp's output to your specific system.

PDX Amplifier Design:
Class-D amplifiers boast higher efficiency, produce much less heat, and draw less current than traditional Class-AB amps. The PDX series is Alpine's totally new super-efficient power density design of full range class-D amps. They combine MOSFET power supplies, MOSFET final outputs, and a thermal management processor, along with a 4-Layer Glass Epoxy PC Board to create a high-end sound quality without the bulky heat sinks required by most amps with this much power.

Marine Ready
The Alpine PDX Marine-ready amplifiers are constructed from UV-resistant materials with corrosion-resistant hardware. The marine coating system helps the amp surpass the specifications for Salt/Fog (ASTM B117) and UV (ASTM G154/D4329) resistance.

STAR Topology
Alpine's unique STAR (Signal Transit for Accurate Response) Circuit PCB design provides a single common ground for all amp sub-blocks, preventing ground interference and minimizing internal noise.

2 and 4-ohm Stable
The PDX mono amplifier can be used with virtually any subwoofers because the PDX amplifier produces the same amount of power into both 2-ohm and 4-ohm, so you will get the most from your subwoofers in almost any application.

Speaker Control
The PDX mono amplifier's groundbreaking damping factor precisely controls the linear movement of your subwoofer giving your system less distortion and more clarity that exceeds other amplifiers.

Subsonic Filter
Also called an infrasonic filter, a subsonic filter cuts off extremely low bass (below the range of human hearing) that many speakers cannot effectively reproduce, thereby making the amp's power supply and output devices, and the speaker, more efficient. The subsonic Filter can either be set to 30Hz, 15Hz or Off.

Low Pass Filter
The amplifier features a built-in Low Pass Filter with a rotary, variable adjustment knob which permits adjustment of the crossover frequency, by rotating the knob to select any frequency between 50 to 200 Hz as the crossover point.
