+12V: The +BATT connector is designed to accept the power cable that connects the amplifier with the positive (+)
terminal on the vehicle battery.
GND: The GND (ground) connector is designed to accept the negative (-) power cable that connects the amplifier to
the vehicle chassis.
REM: The REM connector is for the connection between the amplifier and the source (head unit) via a REM or REMOTE
output on the head unit. This switches the amplifier on automatically when the source (head unit) is switched on.
POWER and PROTECT: These indicator lights are for checking that the amplifier is working correctly.
The POWER light, continuously lit, indicates that the unit is working correctly.
The PROTECT light, continuously or intermittently lit, indicates that the product is working abnormally. Refer to
troubleshooting in 5.
FUSES: The FUSES connector is for holding the amplifier fuses. Ensure that any replacement fuses perfectly match
the amperage of the originals.
5 - Troubleshooting
The statuses of the various LEDs are used to indicate certain failure modes or causes of breakdowns.
Check all possible cases below. If, after these checks, normal operation is not regained, please refer the issue to your
FPX amplifier's installer or dealer.
