Polk Audio PA330.2 2 Channel Amplifier
Power and Style that Amplifies
The PA 330.2 is a two-channel class A/B amplifier with built-in fully variable high-pass and low-pass crossover capable of producing 75 Watts x 2 RMS continuous power @ 4 ohm. It's also capable of bridged one-channel operation with a maximum power of 300 Watts into 4 ohms.
・Speaker level input connects 2 ohm stable stereo operation is capable of driving virtually all automotive speakers.
・High-speed MOSFET switching power supply and high current bipolar output transistors pump maximum voltage and high current to your speakers or subwoofers.
・Double layer fiberglass epoxy printed circuit boards for more rigidity, less shrinkage and a smaller overall amp footprint.
・6-way Smart System Protection (SSP) circuits
・Selectable 12 dB/octave high or low-pass crossover with fixed crossover frequency.
・Switchable 3-position bass boost (0dB, 6dB, 12dB) for extra bass thump.
・Variable input gain optimizes match with different signal sources (175mv to 8V).
・RCA outputs for easy daisy chaining of other amplifiers.
・Mounting hardware with rubber isolation grommets and extra fuse included.
・Multi-color status LED gives instant information on amplifier operation.
