Features
Inputs: The amplifier offers both RCA line-level and speaker-level inputs for 2 channels. The supplied speaker-level input harness allows you to connect this amplifier to a receiver without preamp outputs; aftermarket or factory. The speaker level inputs will accept the output from a high powered radio.
Controls
Low Pass Filter: The amp has a low-pass filter, continuously variable from 50-200 Hz with a slope of 24dB/octave. This being a mono subwoofer amp, the crossover is always engaged.
Subsonic Filter: This amp utilizes a subsonic filter to eliminate super low frequencies that can rob power and damage speakers. The subsonic filter settings are 15 Hz, 30 Hz, and off.
Bass EQ: The Bass EQ circuit provides a variable boost (0-12dB) with an adjustable center frequency (30-80 Hz).
