1 Speaker Terminals

These terminals are 14K Gold plated for high conductivity and minimum impedance loss. The terminals face upwards for easy wiring in tight situations.

2 Fuse

Protects the amplifier as well as the automobile electrical system from short circuit conditions.

3 Power Supply Terminals

4 Input Level Control

Use this control to match the output of the head unit to the amplifier. If distortion is present, reduce the setting of this control.

5 Crossover Mode Switch

In a full range system, set this to FULL. If the amp is being used to power a crossover system, set to either HPF or LPF as needed.

6 Bass Boost Control

Allows you to increase the bass signal level sent to the speakers

7 Low Pass Control

Permits you to adjust the crossover frequency from 35 Hz to 400 Hz to suit the subwoofers

8 High Pass Control

Permits you to adjust the crossover frequency from 80 Hz to 2.5 kHz to suit the tweeters

9 High Level Input (Low Impedance)

Use these if your car stereo does not have

RCA output jacks: connect the speaker output from the head unit to these inputs

10 Low Level Input (High Impedance)

This unit is provided with gold-plated RCA input jacks. Using RCA-RCA type patch cords, connect these inputs to the RCA outputs from your head unit.

11 Power LED Indicator

This LED is illuminated when the REMOTE ON system is turned on.

12 Protection LED Indicator

The protection circuitry in the amp will disable it if it senses an input overload, speaker short circuit, or thermal overload conditions. Should this occur, the PROTECT LED will be illuminated. At that time, it is important that you check to determine what has caused the protection circuitry to become activated.

If the amp shut off because of a thermal overload, allow it to cool down before attempting to restart.

If the shutdown occured because of an input overload, or speaker short circuit, be sure to correct these conditions before attempting to restart the amp.

To reset the amp, turn the REMOTE power off and on again.

4 Input Level Control

Use this control to match the output of the head unit to the amplifier. If distortion is present, reduce the setting of this control.

5 Phase Shift Switch

Allows you to change the phase of your subwoofer from 0 degree to 180 degrees to help compensate from timing difference between drivers.

6 High Pass Subsonic Filter

Adjustable from 15Hz to 40Hz with a slope of 24dB per octave.This allows for the attenuation of frequencies that are mostly inaudible and cause unnecessary strain on the amplifier.

7 Crossover Low Pass Filter

Adjustable from 20Hz to 250Hz with a slope of 24dB per octave.This allows for the adjustment of the upper point of the frequency bandwidth and the respective subwoofer.

8 Low Level Input (High Impedance)

This unit is provided with gold-plated RCA input jacks. Using RCA-RCA type patch cords, connect

these inputs to the RCA outputs from your head 5 unit.

9 Low Level Output (High Impedance)

This unit is provided with gold-plated RCA Output jacks. Using RCA-RCA type patch cords, connect these Outputs to the RCA Inputs for your anyther amplifier.
