Car Audio Noise Troubleshooting

Car Audio Noise Troubleshooting

By Eric Glynn


Noise in your car radio can come from many places inside the vehicle and underneath the hood. The sounds could be whines, clicks, rumbles or only plain old static. Is the sound on your AM radio or on the FM stereo? Would it be observed if you are playing a tape or CD? What form does it take? These are only some of the many questions you can reply with a few simple checks. Most are not required as well as a do-it-yourself car audio checkup can probably locate the difficulty.

Check the antenna. It's out in the weather, in the event your car antenna is mounted in the chassis. Rain, wind, snow and sleet can give rise to a connection issue. Do you have a flag, blossom or other object mounted in the antenna? Wind pressure in the object could cause undesirable vibrations that can loosen the antenna connection.

Try to change the antenna to see whether it truly is loose. If it generates static, tighten the link.

AM radio is Amplitude Modulated and will pick up motor sound in the event the radio is poorly grounded or whether new spark plug wires are needed. Make sure the ground wire in the rear of the radio is tightly linked to the chassis.

A high-pitched whine could suggest a badly grounded alternator.

Turn the radio on with the engine turned off and utilize the turn signals and brakes. Clicking sounds could indicate a bad ground to the radio.

Resolve most vehicle audio problems by examining the integrity of the ground connections to the sound producers like spark plugs, alternator, heater and air conditioner motors in the car. Connections for most parts of your own vehicle's electrical system should be great along with the integrity of each and every one should be checked until the supply of your own sound sound is found.

When possible, practice the engineer's onehand rule when working with electrical wiring. Keep one-hand in your own pocket when working with any cable carrying an electrical charge. This will help you avoid electrical shock. Use caution when checking any electrical wiring. Do not run the engine within an enclosed room while doing your audio assess.
