Alpine® 4 Channel Power Density Digital Car Amplifier

4-channel powerhouse

The PDX-F4 4-channel amplifier delivers 100 watts per channel to your speaker system from its amazingly compact body. You can also switch to 2-channel mode, and drive a couple of subs with 200 watts each. Beefy internal components and clever engineering keep the power output strong and the noise low for superb fidelity and control. The adjustable frequency filters tailors the amp's output to your specific system.

Front-mounted controls and pop-out connectors

Front-mounted controls make post-installation adjustments a snap, even when multiple amps are stacked together. Nifty removable speaker and power wire plugs make it easy to install or remove an amp, while ensuring a tight connection and guaranteeing that your speakers work in unison. Gold-plated RCA inputs, outputs, and power connections resist corrosion and signal degradation.
