Install car ground loop isolator

You may have a self-grounding ground loop isolator, in which case you can ignore this next step. The easiest way to tell if you have a self-grounding model or not is to see if it has any additional wires as well as the jack leads protruding from it.

If it does have additional wires then it is not a self-grounding model and you will need to ground it yourself. There are two ways to ground the ground loop isolator using these wires. The first way is to screw them into any clear metal area on your car. This will ground the ground loop isolator and ensure that you no longer have your sound issues.

The second way to ground it is to screw the wires into the negative terminal on the amplifier. Once you have carried out one of these choices your audio system will be grounded properly and you can enjoy your music once more.

If this still does not cure the problem then you may have your power cables and jack leads too close together, at which point you will need to move one set of wires to another side of the car to alleviate this issue.
