Amplifiers

If you want to get the maximum performance from your loudspeakers and subwoofers, definitely add a Polk PA D amplifier or two. We offer 2-channel, 4-channel, 5-channel and monoblocks. Each PA amp is styled lean and plays meaner, with enough big, fat juicy watts to drive your system so you get to hear all of your music, no matter where and how loud you like to play.

PA D2000.2 2 Channel Amplifier

Super-efficient class D bridgeable 2-channel mobile audio amplifier

The PA D 2000.2 is capable of bridging a left and right terminal into a single full range channel with higher output power. For instance, the L-/R+ channels when wired correctly will increase the output power from 125W per channel to a 500W channel (for a 4 ohm load). The most common hookups are two full-range channels or a bridged subwoofer channel.
