There are two things occurring...may be related, may be coincidence, I don't know.


Problem number one....the speakers on the left side of the car are putting out less sound than the right side...seems to me the bad side does not have any of the high range sounds coming out.


Problem number two...for the past couple of days...around the same time I noticed the speaker differences, I also noticed that with AM radio there is noise and static...noise stops if I turn off the car and listen to AM radio.


Ground issue the most likely culprit? Something else?


If ground where should I start looking....back by the amp...under hood...??


Thanks
