As above, Im using a Kickers amp and thats in working order as i have tried in a mates car. As soon as i replace the fuse within minuits the fuse is blown, i checked for any short circuits cant find any. I have the earth wire attached to bolt holding the rear seats in place. The setup was working fine, been having the problem for the last month. Any suggestions, is it worth me replacing the power cable ? find somewhere else to earth it ? its driving me maddddddd

Many thanks
