[QUOTE="audiolife, post: 6026123, member: 541383"] Bad wire job between batteries...If a battery emitted noise it would emit through the frame as they would be connected to the chassis ground..........If you drive a car newer than 1985 you more than likely have a unibody car where you are not connected to the "frame" as you might think. People also say that running ground wire front to back is bad because it is not "short" if this were true your pos wire would be bad as well as all a circuit is is an electrical circle and if its good for one side it should be good for the other .......
