Car Audio Technical Frequently Asked Questions as well as their answers...
1) Having only installed my new radio, after i power it down and back on again the preset stereo and other settings reset and also the CD ejects. How can this be? This can be an easy task to correct. Basically 2 wires about the radio harness need swapping around. Fundamental essentials 12V permanent
live (yellow wire) and the 12V ignition live (red wire).

Induced Noise can seem like clicking, popping, whirring, buzzing, whistling, or whining. This noise always has a source including the alternator, car power wiring, or amplifier, etc. Which means this means that the situation may be tackled at the source you now have to think it is.
Powerline noise problems for example alternators could be fixed with the help of a capacitor or powerline filter on the live source towards the suspect component. Another method to investigate is the earth or also referred to as ground wire for the rear from the radio or head unit. Try owning a new earth or ground wire in the rear of the radio to a different position (earth) around the cars chassis replacing the existing earth wire.When you have installed an
