Serious mobile audio freaks know that the only way to get the most out of your 12V system is to feed it a healthy dose of clean, efficient power. The best way to do that is with Polk PA D Series amplifiers. These are the amps that push your speakers to reveal all the music in your music. Serious about your vehicle’s sonic performance. Wire up a PA D amp.

Sleek. Compact. Powerful.

When install space is at a premium, but your sound system demands plenty of power to realize its full potential, Polk’s new super-efficient D Series amplifiers are a very cool solution. All D Series 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. 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 the new PA D Amplifiers your high-performance choice for clean, distortion-free sound.

Technology & Features

This is how you build a really cool amplifier.

Every PA D Series amp uses a high-speed MOSFET switching power supply for fast response and high efficiency. Another plus, MOSFETs generate very little heat to keep your PA D amp nice and cool even when their bipolar output transistors are putting out max voltage and high current to your speakers or subwoofers.

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 D 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 D amps come with plenty of protection

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

Anodized extruded-aluminum housings and stainless steel hardware

PA D 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 D Series amps are all about performance pure and simple

An amplifier’s real story is told in its specifications. So choose your favorite D Series 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.
