Well. I removed the connector on the speaker and the amp. Sprayed both with electrical contact cleaner approximately a week ago. I’ve since been away in the car and spent a lot of time in it. Since the above, not one need to belt it. It’s been perfect! Maybe a bit like that fixed my issues with the steering wheel controls, it has also fixed this. Does LR have an issue with electrical connectors getting gummed up? Seems like it. Weird, but so far so good!
