a mate of mine has interference on his cd player when driving ( accelerateing ) , and was going to get one of those little supressor things , looks like a condensor , but where exactly do they go ?
Get an in line one and put it in the power feed to the unit, most importantly make sure the player is well earthed seperately from anything else, also put one in line to any amplifier you may have and same again with the earth, and lastly the aerial earthed well.
