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.
