PA mobile audio amplifier are high speed MOSFET amplifiers that will provide all the high-performance juice you need to ensure your car speakers perform to their full potential. PA amplifiers represent a new generation of compact, super efficient power sources created for the budget-minded enthusiast who desires uncompromising performance from their car’s sound system. Yet they’re powerful enough and loaded with features that the serious audiophile can do battle with at a competition. The amps’ sleek designs work in any kind of install, from retro American classics to high performance European machines.

Moblie Power and Style that Amplifies

When install space is at a premium, but your sound system demands plenty of power to realize its full potential, Polk Audio’s new super-efficient amplifiers are a very cool solution. All PA amps offer an ultra-compact, minimalist design and come in 2-channel, 4-channel and monoblock configurations, as well as a big gun 5-channel beast that enables you to drive all your speakers and a subwoofer. Our PA D Series features Toroidal transformers help keep the amplifier’s sleek aluminum extruded design under 2 inches tall while ensuring plenty of clean, efficient power. Low THD’s, high signal-to-noise ratios rated at full power, plus wide bandwidths, make our PA D amps your high-performance choice for clean, distortion-free sound.

Technology & Features

Efficient circuit board design helps create a more compact amplifier.

Double layer printed circuit boards provide more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. PA amps are very compact, and their efficient layout houses more circuitry, with tighter component tolerances, onto a smaller circuit board, helping create a smaller overall footprint.

PA amps come with plenty of protection.

We know how hard you like to play, so every PA Series amp comes with Thermal, DC offset, reverse DC voltage and short circuit protection.

Anodized extruded-aluminum housings and stainless steel hardware.

PA Series amps are built tough with anodized, extruded aluminum covers and rugged end caps. Cooling fins along the length of each amplifier’s main housing ensure ample heat dissipation. The end caps also protect connectors, while stainless steel hardware is used throughout each D Series amp to provide years of corrosion free performance.

PA Series amps are all about performance pure and simple.

An amplifier’s real story is told in its specifications. So choose your favorite amp, and check out its specs. You’ll find gobs of performance and all the controls you need to tailor your system to your vehicle’s listening environment.
