Is there a way through Techstream to test the speakers throughout the vehicle? I've suspected since I bought my LX that the audio wasn't exactly right. This morning I was poking around trying to see if I could get the front camera working when I noticed the lower driver door speaker wasn't working. In checking the other doors I found that none of the lower door speakers work. The upper door pods are fine on all doors. I hooked up Techstream but didn't see anything obvious for audio. Is there an easy way to test/check the speakers without pulling the door panels?
