Polk Audio PA D4000.4, PA D Series 4-Channel Amplifier, 800 Watts RMS
Sleek, Compact, Powerful, and Really Cool
The PA D4000.4 amplifier is capable of bridging two full-range channels into a single full range channel with higher output power. For instance, one front and one rear channel will increase the output power from 125W per channel to 400W per channel (for a 4 ohm load). The most common hookups for the PA D4000.4 would be four full-range channels, two full-range channels and a bridged sub, or two bridged subwoofers.
PA D4000.4 Features:
Super-Eefficient Class D Design Runs much cooler than conventional amps.
Toroidal Transformers Help keep the amplifier’s sleek design under 2" tall while ensuring plenty of clean, efficient power

Nickel-plated wire terminals & RCA connectors Ensure maximum signal transfer
Front & rear level controls Adjust the gain of the front and rear channels to match the output voltage from your head unit.
