So my sound quit, followed by several cracks and pops from the speakers making me think I was being shot at.
The head units work fine, all displays and graphics normal.
I suspect the amp unit fried (although I'm not sure why)
Is there an aftermarket rewire/swapout option?

Thanks

 

i have heard it is quite costly to replace the amp section.

 

If you go to the Levinson website they show authorized repair facilities.
