[QUOTE="bubbagumper6, post: 8278511, member: 567719"] I guess I should add to my earlier statement. The fuse is there for two different scenarios. 1. Your wire gets pinched/cut/etc and shorts directly to ground. In this case you need to protect the power source (battery or alt) so the fuse should be as close to it as possible (to minimize the length of unprotected wire). 2. Your amplifier attempts to draw more current than your wire can handle. In this case you're fusing to protect the wire itself so the fuse size should be the maximum current the wire size can handle safely (or smaller). The first scenario determines WHERE you should place the fuse (close to the power source) the second scenario determines the actual fuse SIZE (in amps). It should also be noted when changing wire size you should fuse at the connection (like in a distribution block) as the smaller wire can handle less current and will need a smaller fuse. [/QUOTE]
