Troubleshooting
Q: My amplifier is connected to the battery, but the indicator light is off and it won't turn on. How do I fix this?
A: Please ensure the REM (Remote Turn-On Lead) terminal on the amplifier is correctly connected. This is a crucial control line that runs from your head unit (main stereo) to the amplifier's REM terminal. It signals the amplifier to power up only when your stereo is turned on, preventing battery drain when the vehicle is off.

Key Features Not to Miss:
- RCA Inputs/Outputs: Seamlessly connect to car receiver or daisy-chain multiple amplifiers using the built-in IN/OUT channel ports.
- Gain Control: Independent gain matching for front and rear channels to prevent clipping and optimize head-unit signal integration.
- Advanced Protection: Intelligent thermal protection circuitry automatically shuts down the amp to prevent damage if overheating occurs, resuming normal operation once cooled.

Important Installation Notes:
- Impedance Limits: When a channel-pair is bridged, the minimum recommended load impedance is 3Ω for subwoofer use and 4Ω for full-range operation. Wiring below these impedances will cause the amplifier to overheat and trigger the thermal protection mode.
- Mounting: Choose a completely dry location with excellent air circulation to mount the unit. Ensure the mounting surface is mechanically stable.
- Wiring Safety: Always connect to a +12V positive battery terminal, secure the negative ground to the vehicle chassis, and properly connect the ACC (remote) wire.
