Polk Audio PA D5000.5, PA D Series 5-Channel Amplifier, 900 Watts RMS

Sleek, Compact, Powerful The PA D5000.5 is capable of bridging two full-range channels into a single full-range channel with higher output power. For instance, the front channels (FL and FR) when wired correctly will increase the output power from 70W per channel to 200W per channel (for a 4 ohm load). The same can be done for the rear channels (RL and RR). The most common configurations are four full-range channels and a subwoofer channel, or two bridged full-range channels and a subwoofer channel. PA D5000.5 Features: Super-efficient class D design—runs much cooler than conventional amps. High-speed MOSFET switching—power supply with outputs stable into 2 ohm loads for full range channel speakers and 1 ohm loads for subwoofer channel. Protection—thermal, DC offset, reverse DC voltage and short circuit protection. Sub 1/Sub 2 Inputs—line level inputs for subwoofer signal from head unit SUB/INT source switch—in the INT position, the amplifier will filter the bass frequencies from t
