    I'll second www.knukonceptz.com. Just got my 4 gauge wire and other items and installed them this morning. I like the Kompression set-up they have. Anyway, if you can draw up a diagram of how you have things set-up I'm sure we can come up with some suggestions. On a single circuit (from the carnetix to your LCD) your fuse needs to be less than the rating of the smallest wire, so that the fuse will pop before that wire burns up from too much current. I would do one 5 amp fuse at the carnetix to lcd power wire right on the carnetix output wire and verify the wire you use can handle more than 5 amps.

    This is contrary to having a fuse every time you change gauge of wire. However, if a 5 amp fuse is connected to a circuit that has 12 then 10 then 14 then xxx gauge, anything that will handle more than 5 amps it will be OK. As long as the fuse will pop before any of the wire in the circuit burns up....

    Existing circuits like ACC are probably already fused...however check the fuse rating and compare to the wire you are using. If in doubt, fuse it. Inline fuse are cheap and easy to install... I just use the walmart inline fuse holders that take the automotive blade fuses.

    Forgot to ask, Where is that 15amp fuse located? You should have a fuse very close to the battery for the 8 gauge...so if the 8 gauge wire shorts out the whole wire goes dead past the fuse.
