Polk Audio PAD5000.5 900w RMS 5-Channel Marine Amplifier Boat Amp PA D5000.5

Features:
Polk Audio PAD5000.5 5-Channel 900w RMS 2-Ohm Car Audio Amplifier Amp PA D5000.5
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 the full range signal and send them to the subwoofer amplifier channel.
SUB Sonic Filter—Attenuates the frequencies below the settings on the control.
Remote Bass Level Control—Set gain to match output from head unit.
Rear Full, HPF Switch—Selects between no filtering or a high pass filter to dial in your speakers' blending.
Channel Mode Switch (4CH/ST)—In the ST position, the amplifier sends the same signal to the front and rear channels.
Nickel-Plated Wire Terminals & RCA connectors— Ensure maximum signal transfer.
Stainless Steel Hardware—Used throughout won't corrode in humid environments.
