Okay, so I was driving down the road when my system turned off. I looked back only to see that i forgot to screw in the 4 gauge power wire so pulled over and tried to screw it back in. During the process I accidently touch the ground wire and the power wire together and it made a little spark. (keep in mind that everything is still connected to my battery) To my dismay my amp wouldn't even power on. I tried troubleshooting by hooking up my old amp. That one didn't turn on either. So then I thought i blew the fuse so i changed out the fuse and even got a whole new fuse holder. still nothing. At this point im very frustrated and have no idea what is wrong. Is there a possibility that my power wire is fried? Thanks for your help
