I had a Tesla style radio installed, and I was adding a loc to the system using the factory sub wires and a wire brushed against a positive speaker terminal. it arched and now I have no sound from any speakers except my aftermarket sub-woofers. I have checked every fuse in the fuse box including the hidden fuse in the inline fuse holder and even the fuse on the back of the radio all are fine. I also pulled the negative battery cable and left off for thirty minutes or so and still nothing. any help would be great.

Hello,

Have you checked for power at fuse # 67 and 71 in the under hood fuse panel? Here is a guide to help test it and the radio wiring diagrams so you can see how the radio works with the fuse locations as well:

Yes, I have checked 67 and 71. every single fuse is good. I even checked the fuse that is not in the fuse box. It's in a in line fuse holder in the cluster of wires by the battery.
