Why won’t the subwoofer turn on?

Check for at least 12V at +12V and a secure GND connection to bare metal. Check the fuse. For REM turn-on, connect REM to the head unit’s remote output. Signal-sensing auto turn-on uses +12V, GND, and audio only.

Where should I connect the +12V power wire?

Connect +12V directly to the positive terminal of the vehicle’s lead-acid battery. Do not use the in-cabin fuse box; it may cause insufficient power, poor sound, or improper operation.

Why is the subwoofer on but producing no bass?

Connect audio to the head unit’s OUT port. Check that the source is not muted, select the correct input type, and do not connect high- and low-level inputs at the same time. Check the line-output converter level and low-pass filter setting.

Why do I hear hissing or unwanted noise?

Check the RCA cable, connections, and RCA ground. Try another cable or audio source. You can also test with a phone and a 3.5 mm adapter; clear phone playback points to the vehicle audio source or wiring.

Why does the subwoofer overheat or enter protection mode?

Reduce the gain and keep the unit properly oriented with space for ventilation. If the protection light is on, switch off the system and check for shorted or exposed wires, secure power and ground connections, and suitable power cable size.
