Note: If your car has fiber optic amplifier, this unit does not work, because it does not support fiber optic amplifier, so there will be no sound after installation if your car has fiber optic amplifier. The small amplifier we provided is used to transfer the sound from our unit to your car speakers through the 8 speaker wires from the factory wiring harness, so if there are 8 speaker wires from the factory wiring harness, your car doesn’t have fiber optic amp, you can see the below picture:
