Sometimes size doesn't matter. You get big power from a little box with Alpine's Power Density Digital Amplifiers. Super-efficient Class-D technology allows these small-but-mighty amplifiers to run so cool they can be stacked together for a sweet multi-amp setup, freeing up valuable space on your boat.
The PDX-4.100M 4-channel amplifier supplies a full 100 watts to each channel, plenty of power for even the most demanding component speaker systems. Switch to 2-channel mode, and you can send 200 watts to each of your subwoofers. Weather-sealed internal components and clever engineering keep the power output strong and the noise low for superb fidelity and control. Adjustable frequency filters tailor the amp's output to your specific system.
Front-mounted controls make post-installation adjustments a snap. Gold-plated RCA inputs and power connections resist corrosion and signal degradation. Nifty speaker wire plugs ensure a tight connection and guarantee that your speakers play in unison.
