PDX-4.100M – Marine 4 Channel Digital Amplifier

Powerful and amazingly capable: The Alpine Marine PDX-4.100M Power Density 4 Channel Amplifier is a durable, reliable digital power station providing over 90% efficiency at all power levels – even with the engine off.

The Marine Power Station

Loaded with 600 Watts of power Alpine's PDX 4.100M Multi Channel Amplifiers play amazingly long and efficient without wasting battery. Alpine's Marine Amplifiers deliver outstanding performance at all volume levels. Engineered for the severe challenges of the marine environment Alpine's PDX-4.100M work with maximum performance and durability.
The PDX-4.100M amps are 60% smaller than previous models with the same output power, which makes it easy to find adequate mounting space. Even two or more amps together make a small package – and, a powerful amp system that installs practically anywhere! The audio and crossover controls are conveniently placed on the front of the amplifier, making them easily accessible for further sound tuning. The Alpine Marine Amplifiers are also perfectly aligned to allow each amplifier to be stacked upon the other.

Marine – Ready

Marine Coating System and ATSM proven Salt/Fog plus UV-light resistance make Alpine's Marine Amplifiers well-prepared for cruising beyond the limit.

Overview

• 100W RMS x 4 @ 4 Ohm (CEA-2006)
• Marine Coating System
• Salt/Fog (ASTM B117) Certified
• UV (ASTM G154/D4329) Certified
• 4/3/2 Channel (bridgeable)

Super high efficiency

Alpine's PDX Marine amplifiers are over 90% efficient at all power levels - drawing less current saving valuable battery power.

Cool running to play

PDX switch-mode digital amplifier technology allows PDX Marine amps to run cool and resist the harsh marine environment.

Greater System Flexibility

Both amps deliver identical output into 2 Ohm and 4 Ohm loads, which allows for greater system building flexibility. An efficient way to get more dynamic bass: the amplifier power can be used to drive either one 4 Ohm speaker or two 4 Ohm speakers wired in parallel.

Power with Extreme Clarity

400 watts of power produce impressive clear and crisp sound. The secret of the clean performance and the effortless power coming from the PDX-1.600M, and the PDX-4.100M is a design that combines improved feedback circuitry and a revolutionary power supply filtering system. In addition they boast a damping factor that is 350% better than Class A/B amps.

Smart Stacking Design Saves Space

All PDX Marine amps have the same size and shape. Using the removable 1” diameter trim caps from their top, they can be vertically stacked on top of each other, sharing one set of mounting holes. This is an industry-first installation option that saves enormous amounts of space. PDX amplifiers are 60% smaller than previous models with the same output power. Install your amps easily without sacrificing valuable room, power and performance.

Build a Full System

To build the perfect individual marine system for every boat the PDX Marine amplifiers are available in a mono and a 4/3/2 channel designs. So for those who really want to embark the ultimate boom on the water, Alpine Marine Amplifiers deliver every time.
