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.

PA330.2 2 Channel Amplifier

High-performance 2-channel mobile audio amplifier

The PA 330.2 is a two-channel class A/B amplifier with built-in fully variable high-pass and low-pass crossover capable of producing 75 Watts x 2 RMS continuous power @ 4 ohm. It’s also capable of bridged one-channel operation with a maximum power of 300 Watts into 4 ohms.
