Alpine PDX-4.100M – Marine

PDX-4.100M – 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 Ω (CEA-2006)
Marine Coating System
Salt/Fog (ASTM B117) Certified
UV (ASTM G154/D4329) Certified
4/3/2 Channel (bridgeable)
HP/LP crossover 30Hz-400Hz variable
