Bass Boost, Subsonic Crossover Frequency

Amplifier Owner’s Manual

BASS BOOST

Variable bass boost from 0 to +18dB @ 45 Hz.

SUBSONIC CROSSOVER FREQUENCY

Controls the highpass crossover point for the speaker outputs to eliminate extreme low frequencies.

12V+

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. 1/0 gauge wire REQUIRED.

REMOTE

This must be connected to switched +12V, usually a trigger wire coming from the head unit or ignition.

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. 1/0 gauge wire REQUIRED.

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 sub channel.

REMOTE MONITORING DISPLAY (RMD)

Connect optional RMD Voltage Display to this port.

PEAK INDICATOR

Lights when the amplifier reaches near maximum output. Under normal operation the peak indicator should be flashing during the peaks of the music. Peak indicator should not stay lit for long periods of time (more than 2 or 3 seconds), if this is the case you need to reduce system volume or level of the amplifier.

PROTECT INDICATOR

Lights red if there is a problem with the audio system, see the troubleshooting page.
