I hooked up my Kicker Sx 1200.1, I ran my wire with inline fuse to distribution block from there to amp.. I ran my ground to a bolt drilled into the floor of my truck I hooked both of these up and my remote wire. I also had my speakers hooked up and my rca's hooked up.. all of my settings were at zero gain...etc. etc. My subwoofer output was turned off on my head unit. I hooked up my power cable to my battery without the fuse in. I then checked to make sure everything was connected and put the fuse in when the fuse was put in the amp started smoking. I pulled the fuse immediately and took it out and pulled covers off and part of the board was black looked like a capacitator on the board was fried it only burnt a small part of the board.. the part where the power came into the amp. I then put my fuse back in and checked my power and ground supply and they were both fine. I used a tester. I think that the amp didnt ground inside of it Bc I had my wires connected fine.. Does anyone know of any reason why this would happen? or if it was a manufactured fault?
