Troubleshooting
- No Power: Check all power connections (+12V, GND, REM IN). Ensure the remote wire is receiving a 12V signal from the head unit.
- No Audio Output: Verify RCA connections from the PX2CONNECT to amplifiers. Check input source selection in the app. Ensure gain levels are appropriately set and channels are not muted.
- Bluetooth Disconnection: Ensure your mobile device is within range and there are no obstructions. Restart the PX2CONNECT and your mobile device, then attempt to re-pair.
- Distorted Sound: Check gain settings on both the PX2CONNECT and amplifiers. Reduce input gain if the signal is clipping. Ensure all filters and EQ settings are appropriate for your speakers.
- Ground Noise/Whine: Ensure all audio components (head unit, DSP, amplifiers) are grounded to a common, clean chassis point. Check for proper shielding of RCA cables.
