My car got broken into two weeks back, and last night so I tried to install these brackets/shields for my amps so they couldnt be taken. While I was drilling a hole i drilled right into my power cord for my speaker amp, not my sub amp. The wire is in ok condition still, I barely made it threw the plastic coating but obviously still hit it. Now I can not get any sound from my speakers or sub. My head unit still turns on.

So, I checked my fuses in both amps and on the battery and all fuses still look good. I replaced the wire with a new one and still no luck. I then replaced my fuses in the amp and still no luck.

The power wire that I drilled into goes from my distribution block to my speaker amp.

Any ideas on what I should do next?
