TROUBLESHOOTING TIPS

With a Volt Ohm Meter (VOM) check

• +12 Volt power terminal (should read +10 to +16V DC

• Remote turn on terminal (should read +10 to +16V DC)

• Ground Terminal

• Check RCA connections

• Test speaker outputs with known good speaker

• Substitute known good Source Unit

• Check for signal on the RCA cable with VOM in AC position.

• Short circuit protection is engaged.Check for speaker

wires shorted to each other or the vehicle chassis.

• Advanced Protection Circuitry is engaging due to high

internal temperature of the amplifier. Amplifer requires

more air flow around the chassis. If this continues

choose a better ventilated mounting location.

• Voltage protection engaged. Voltage to the amp is not

within the 10-16 VDC operating range.

Have the battery/ charging system inspected.

• Possible short circuit. Check speaker wiring. Must

completely turn off amplifier and restart to resume play.

• Check for damaged RCA cable.

• Check routing of RCA cable

• Check Source Unit for good ground

• Check amp gain setting, turn down if set too high

• Check speaker polarity, reverse the connection of one

speaker only.
