Small amp — massive power

Polk's PA D1000.1 mono sub amplifier may be small, but it can send up to 1200 watts RMS to your sub setup. This little beast can handle loads as low as 1 ohm, so it can also handle virtually any combination of subs you can imagine. And, this amp will fit in almost any location in your vehicle because of its convenient size and shape.

Powerful bass from a stainless steel case

Polk developed and employed their Class D amp technology to help this amp reproduce bass very cleanly, with no added coloration or distortion. Adjustable low-pass and subsonic filters, along with a bass boost, help you to tune your sub system to sound its best. The amp comes with a wired remote, so you can control the subwoofer level from your front seat. This amp's tough, good-looking stainless steel case won't tarnish, even in the most humid conditions.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.
