The MODE switch will sum or combine the right and left channel signals in the 2CH position to improve bass performance when bridging the amplifier to mono. Use the 4CH mode when driving four full range speakers.

Set the crossover switch to LP, ensure the crossover frequency is set at 100Hz or below. This feature must be used with a subwoofer to filter out all mid to high frequencies that only full range speakers should produce.

Set the crossover switch to HP and turn this control to 65Hz or above when using speaker’s smaller than 6 x 9”. When a subwoofer is used in the system, this feature is designed to filter out all low bass frequencies that only subwoofers should produce.

This is a critical step to insure your amplifier is properly adjusted to match the signal output level of your source unit.

THIS IS NOT A VOLUME CONTROL

This control is used to match the input level of the amplifier to the output level of your head unit. We recommend the method below, as failure to follow these steps may damage the audio system.

1. Turn the amplifier Gain to zero2. Turn the volume of the head unit to ¾ and the bass and treble to zero3. Adjust the amplifier Gain/Level control until the desired maximum volume is achieved without distortion.4. Make fine adjustments to tune your install.

PROBLEM POSSIBLE REASON SOLUTION

Amplifier not switching on. LED = OFF (not ‘Red or

Green’)

• No +12V to power wire

• Check fuses and connections to battery

• No power to remote wire

• Check Remote Turn ON connection(s) to head unit

• Fuse broken • Replace fuse with correct type and amperage

• No Ground connection

• Check ground cable is correctly connected to the amplifier and vehicle / body chassis

Amplifier not working, status

LED = Red

• Amplifier too hot • Move amplifier to vented area • Turn head unit down

• Speaker wires shorted • Check that there are no speaker wires shorted to another wire or to the vehicle chassis

No soundLED = Green

• RCA Signal • Check RCA connection to head unit

• Gain control not set up

• Ensure you have set up the amplifier gain level control

• Head Unit • Check head unit volume level

• Amplifier • Check all power, remote on and ground connections

• Speakers • Check speakers are correctly connected.

• Check speakers for wire shorts
