[QUOTE="jb2xx, post: 699236, member: 556714"] For what your friend is going to be running, I would recomend 4guage. Don't even consider 8guage. If I were him, I would even maybe consider 2guage from battery to terminal block. From terminal block to 300w amp I would do the 4guage. For the 750W amp, I would go 4 guage as well. The fuses are to protect the wires since the amps already have fuse protection. It is recomended that the primary fuse be as close as possible to the battery within or less than 12 inches. 100A fuse at the battery I suppose would be ok. At the terminal block, I would do 40A for the 300W amp & 60A for the 750W amp. If anybody has other suggestions, please provide your input. If fuses begin to blow, it's a sign of a grounding problem. Not so long ago I had a grounding problem on my fused distro block. [/QUOTE]
