The Polk PA D4000.4 4-channel amplifier may be small, but it can power your front and rear speakers with up to 125 Watt RMS each. Alternatively, you can switch this little beast to 2 channel mode to drive two subwoofers with up to 200 Watt RMS each. This amplifier fits in almost any position in your vehicle due to its appropriate size and shape.
Great look and clear sound.
Polk has developed and used the complete Class D amplifier technology, which helps this amplifier to play clear music without any additional coloring or distortion. Separate high- and low-pass filters on the front and rear channels allow this versatile amplifier to run a variety of speaker systems, such as mid-bass and tweeter components, or two front speakers and one secondary. The hard, beautiful stainless steel case of this amplifier will not get dirty, even in extremely wet conditions.
