All installed now, but very loud intermittent static when there is any movement, even the steering wheel – suspect speaker - when I tap on the speaker screen it does (Chrome grill not in place yet) give really big static with each tap, until I stop. It is hooked up now to the ammeter.
I didn’t move it around at all when I was bench testing. The volume control also wobbles a bit and causes some noise while adjusting, but but nothing like what happens when tapping the speaker even lightly. Sounds like it’s back to the bench.
