So I'm not sure if this goes here but here is my issue. I have a Kenwood XR600-1 and i had it out and when I went to hook it up with out thinking a put my power wire in first while it was connected to the battery and then i put in the ground and sparks. I checked the 3 30amp fuses and all 3 where blown so i replaced them and it sparked again and blew all 3 fuses again.So im just trying to get maybe an idea of how bad my screw up was. Also the inside of the amp doesnt look burnt and it doesnt smell fried but the ground terminal is kinda black. Any feedback is appreciated.
