10 out of 10 to HP

I finally managed to see another audio specialist and he immediately picked up on the Bose amp being active all the time. He believed the Bose harness being used was faulty and wasn’t switching off the amp and it was permanently live just as HP said. He swapped over to a new harness that runs from the headunit pre outs instead of the speaker wires. The trade off is a small thump sound as the amp powers on/off but I can live with this for now. To eliminate that I would need to swap out my speakers and Bose amp to an aftermarket set.....watch this space!

I’ll monitor over the next few weeks as I only had it done yesterday but the technician who fixed it is confident this will be it. Fingers crossed and thanks to all who gave input.
