Problems
My speakers make a buzzing noise when i rev the engine, or just constantly buzz no matter what i do
My speakers are crackling and not producing sound like they used to
My radio forgets its settings each time i switch off the cars engine
If your radio is forgetting its setting the most likely cause is that the wiring is backwards, or not connected properly.
Try switching the red and yellow wires; these should be live or permanent live. Check these with a multi meter before swapping them to avoid blowing fuses.
If this does not solve you problem it may be because a wiring adaptor is wrongly wired for your car. Try testing for which wires are live, ignition live, and earth.
Questions:
