What should I do if my car stereo is making noise?
If the car computer (or other motor-less accessory) is causing the problem, move your receiver’s wiring away from that accessory to minimize the radiated noise. Try using magnetic shielding foil (also called Mu-metal) to shield the back of the receiver or wrap the wire or component that’s radiating the noise into your system.
What should I do if my audio system is making noise?
Your ground wire should ideally be 18″ long at most — a longer ground wire can cause noise problems. Improper grounding causes most system noise problems. If you have an external amplifier in your system, the first thing to do is to quiet any system noise, which sounds like a constant, low hiss. First, check for system noise with the engine off.
Why does my car make noise when I play a CD?
If the noise isn’t coming in through the antenna, try pulling the receiver from the dash while a CD is playing. If the noise goes away, it’s being radiated into your system due to the receiver’s proximity to a noise producer (like a heater motor or car computer). This is often referred to as “sideway noise.”
