For what your system consist of one run of 1/0 is fine. Thank you. I'm also from Detroit. Nice to meet you Link to comment Share on other sites More sharing options...
Jonathan Mills Posted November 17, 2017 Report Share Posted November 17, 2017 You absolutely without a doubt do need 2 fuses. You need a fuse within 1 to 2 feet of any hot wire coming off any battery especially a wire that is run the length of the vehicle whether outside on the frame or otherwise. A fuse on the battery under the hood is not going to do anything but keep the front battery charged for the fire that will ensue as soon as the trunk battery shorts out and burns your car to the ground.

mpulford311 Posted November 17, 2017 Author Report Share Posted November 17, 2017 I do have a fuse from the alt to battery I do have a fuse from front battery running along vehicle to another fuse then to back battery. I even have fuses from battery to my dual inputs on my amplifier. I got fuses everywhere. Lol Link to comment Share on other sites More sharing options...

The isolator is not going to serve a purpose unless you play your music with the car off. But to clarify... IF you run your system with the car off, you want an isolator so that your under-the-hood battery is not affected while you drain your trunk battery. Not even needed then. And if you were to do something like that and drain that rear battery bank and then start the car up your alternator is going to hate life. Alternators absolutely do not like having to charge a dead battery, its a good way to burn up an alt. You shouldnt be blasting your system with the car off to the point of even draining the battery bank that far ever anyway, your amps will not appreciate the low voltage. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
