Hey again everyone,
When I bought the car, previous owner told me about the popping sound and as days go by it’s starting to bug me more and more. Whenever I turn the key (whether I start the car or just turn electronics on), the popping sound occurs once. It sounds like it’s coming from the rear speaker (similar to someone hitting the trunk with a hammer lightly). I saw a thread on e46fanatics about it but there wasn’t too much detail there.
Anyone have this issue on where should I start first? I’m thinking the ground wiring for amp but not sure where that is located.
Thanks in advance for your help.
