I checked all of my connections. I get between 12-13 volts from the power cable. The problem is once I plug the power and the ground wire into the amp it sparks, and eventually a fuse blows. My ground wire is about 2 ft long and never touches the power wire. The fuse that blow is not the inline fuse, but is the fuse on the amp. I tried connecting another amp, but the protection led is lit. And eventually the fuses blow on the amp also. If u can help please reply.
