If you have a spare battery you could always quick wire it up with a new power, ground and remote wire. This will isolate any possible other issues with the bike.

Thanks bud, I had it all wired in on my bench with same protection codes
14 then one 12.
According to ARC Audio sheets, that's a voltage overload and a short. I tried everything to ensure it was in fact the amp and not some stupid Sandhog ****. I'm not sure exactly how long that mouse was in there, but he had chewed the left speaker wire between the crossover and the Focal 165KRC before it entered the pod.
BTW I'd bought the system from Sounds Customz back in 2015. I emailed Pete Jensen the owner yesterday and got an immediate reply. He suggested numerous things to try, even though it was a holiday weekend. Amazing dude with fantastic support.
I'm waiting to hear back from him about buying a new amp and a Focal K2 crossover.
Again thanks all for the posts.
