[QUOTE="DidUHearThat?, post: 4690347, member: 594758"] Well I woudn't do that either. [IMG]//content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif[/IMG] I'm just pointing out to the OP that, IMO, a 200 amp fuse is too big for what is really a 70 amp system. Even though the wire can take it, and the battery can occasionally deliver it, it would be safer to go with a smaller fuse. Anything from 100- 160 would be fine, but a 200 amp fuse is almost 3 times the nominal capacity of his system. There is no reason for that. Most people just slap in what ever fuse came with the holder, which is certainly better than nothing, but a properly designed system should be as exact as possible. I have a 120 amp system; a 120 amp alternator, 125 amp fuses, 4 gauge cable, and 85 amps of audio. With 2 batteries I can slam my system while starting the engine without fear of blowing anything, but the fuses should trip quickly if anything goes wrong. [/QUOTE]
