please, help me out, My current setup is not working, 4 gauge wire from battery to block in back, then it splits up into 8 gauge and so on. My sub puts out over 1000 rms, look at sig for equipment. I keep blowin my fuse on the battery, someone on here told me to get 0 gauge wire, but how would i do that, 0 gauge to block than 4 gauge? or how does the wire setup breakdown?
