Alpine introduces its award-winning line of Marine sound system
products. Whether you want a simple sound upgrade for your runabout, a
high-quality system for your cruiser or sportboat, or huge output for
your ski/wakeboard boat, there is an Alpine Marine system just right for
you. Constructed from UV resistant materials and finish, and corrosion
resistant hardware, these bad boy amps are ready to rough the seas. Accurate Dynamic Sound Reproduction
Alpines 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 youre 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! Accurate Dynamic Sound Reproduction

The PDX amplifiers unique design allow for a clean, easy, and
fast install. All the controls and wiring connections are in one
convenient location. Save SpacePDX
amplifiers are 60% smaller than previous models with the same output
power. Install your amps easily without sacrificing valuable room, power
and performance. Smart StackingThe
PDX amplifiers feature a smart stackable design. All PDX amplifiers are
the same size, regardless of the amount of power or channel
specifications. Their 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. Low Resistance, High Current Speaker TerminalsQuick disconnect plugs with low resistance and high current capabilities make installing quick and easy.
More Power, Better Sound
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. Unprecedented Sound MatchingAccuracy
A highly effective Powerful Feedback Circuit accurately compares the
amplifiers output against the original music signal. If there are
any differences found between the two, the feedback circuit
automatically removes the distortion in real-time! This keeps your music
true to the original recording without added distortion or filter
noise. Same Power Output -2 or 4 Configuration
PDX
amplifiers have the unique capability to deliver the same power output
regardless of 2 and 4 loads. This provides the ultimate in system
flexibility and subwoofer configuration diversity. Power On Demand*
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. *Full Range PDX Amplifiers Only (PDX-4.150, PDX-4.100, PDX-2.150
