Alpine® Mono Power Car Amplifier

Model #: PDX-M12
At a Glance
Alpine packs Class-D amplifier technology into their PDX amplifiers for awesome power from a 2" tall frame. These small-but-mighty amps run so cool they can be stacked together into a single unit — their heatsinks couple together to cool the entire stack. Each amp offers an 8" by 10" footprint, so they'll fit in hatchbacks, trunks, truck cabs, and any vehicles with limited space.

Get to know this product.

Winner of a 2010 Innovations Award, the PDX-M12 mono amplifier supplies a stunning 1,200 watts of sub-cranking power from its amazingly compact body. Beefy internal components and clever engineering keep the power output strong and the noise low for superb fidelity and control. The adjustable low-pass filter 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.
