OUTPUT
Provides a full range signal for an additional amplifier. There is no signal loss if using this output.
LEVEL
Used to reach maximum amplifier power with a wide variety of headunits.
CROSSOVER FREQUENCY
Controls the lowpass crossover point for the speaker outputs.
BASS BOOST
Variable bass boost from 0 to +18dB @ 45 Hz.
LOW PASS LEVEL CONTROL (LPL)
This port is for connecting the optional remote level control (LPL44). This allows up to 20dB of volume adjustment. This is not a bass boost, it
controls the level of the low pass signal.
HI INPUT
Connect a factory system’s headunit or amplifier outputs. Using the HI level input the amplifier will automatically turn on and off using the factory system’s audio signal as a trigger. The high level auto on switch turns off the auto turn on function, but the high level input still works as normal.
SUBSONIC CROSSOVER FREQUENCY
Controls the highpass crossover point for the speaker outputs to eliminate extreme low frequencies.
12V+ | SPEAKER OUTPUTS |
This must be connected to the fused positive terminal (+12V) of the car’s battery. The fuse must be located within 18 inches of the battery.
Used to connect the amplifier to speakers. R250.1 and R500.1 minimum impedance is 2 ohm, R1000.1 is 1 ohm.
REMOTE
This must be connected to switched +12V, usually a trigger wire coming from the head unit or ignition. This is not used if using Hi input auto on feature.
GND
This must be connected to the negative terminal of the car’s battery or bolted to a clean, unpainted part of the chassis of the vehicle.
