  If your In Phase Car Receiver has no audio, it could be due to several reasons: low or no remote turn-on connections, a blown fuse, disconnected power wires, or blown or disconnected speakers. Check the remote turn-on voltage at the amplifier and head unit. Replace any blown fuses with new fast-blow fuses. Check butt splices or solder joints, and inspect the ground and battery connections. Use a VOM or DVM to measure speaker coil impedance and check speaker wiring connections.

  If you are experiencing a whining noise on the audio of your In Phase Car Receiver when the engine is running, it's likely that the amplifier is picking up alternator noise. To resolve this, try installing an in-line noise filter on the head unit's power wire. Also, check the alternator routing diodes or voltage regulator for proper operation, and inspect all grounds, battery voltage, and RCA cables.

  If your In Phase Car Receiver is producing distorted audio, it could be due to the input sensitivity not being set correctly or damaged speaker cones, or even low turn-on voltage. You should check the adjustment procedure step by step. Inspect each speaker for damage and repair or replace any damaged components. Also, refer to the head unit owner's manual.

  If you are experiencing a ticking noise on the audio of your In Phase Car Receiver when the engine is running, the amplifier might be picking up radiated spark noise. To fix this, check the RCA audio cable and install an in-line noise filter on the head unit's power wire. Also, inspect the spark plug wires.
