component cable splitter best buyFault Questions:

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). Remove your radio and disconnect the bullet connectors found on the radio wiring harness and swap these 2 colours, to ensure that yellow would go to red and red would go to yellow. Your radio was simply losing power to the memory feature.

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.

With regard to testing, try running the RCA lead loosely between your head unit as well as the amplifier without actually running them under the carpet. Rev your engine with all the radio on low volume and see if the noise went. When it has tried running the RCS's employing a different route along the car.
