I am having the same issue. I have to adjust the windows volume balance in order to not feel the difference. I am not sure why is that happening.

Answer 3

Currently having this problem, bought as a minor blemished product from AMS and has worked well for 10 days. I had to resort to balancing volume level as another user had mentioned. Hope that there is an actual solution to this, unless that this is a product defect. Tried a new speaker wire but no change.
