i have no idea if this is normal i left station on AM and reved me engine and the MP3 player played my engine throught th speakers it sounded BAD ***! it zipped as i gave it gas i drove around and it was still the same noise coming from my speakers i changed to FM it went away until i went to weak fm station and it went zoom zipp zip out the speakers as i gave it gas?

Is this normal or is somthing wrong........

also i plan i getting new grounds for my car where is good plce to buy grounds cables, - & + cables

 

New spark plug wires fixed that problem for me, must have been getting worn in their old age.

Better grounding is needed.
