PA D4000.4 PAD Series 4-Channel Amplifier - 400W
When install space is at a premium, but your sound system demands plenty of power to realize its full potential, Polk Audio’s new super-efficient D Series amplifiers are a very cool solution.
Polk's PA D4000.4 4-channel amplifier may be small, but it can power your front and rear speakers with up to 125 watts RMS each. Or, you can switch this little beast over to 2-channel mode to drive a couple subwoofers with up to 200 watts RMS each. However you use it, this amplifier will fit in almost any location.
Separate high- and low-pass filters on the front and rear channels allow this versatile amp to run a variety of speaker systems, like bi-amped mid-bass and tweeter components, or two front speakers and a sub.
