I just installed a second battery and isolator and am currently wiring up all the parts I’ve been collecting, such as a amp, speakers, LED’s, whips, etc. I am running all those off a fuse block under the hood that is wired to the factory auxiliary power bar. My question is should I move that aux power wire to the second battery that way if I leave the music on it doesn’t kill my main battery. I think it would be best to do so, but the factory wire doesn’t have much slack. Would it be best to just remove it and put a longer wire in its place and run it to the second battery? I think it’s just 4 gauge power and ground wire. I would just add on to the existing aux power wire, but I’m not a big fan of having a lot of wire extension connections. Not that it makes a difference, but I have a ’17 Turbo.
