Alright, so I am throwing back and forth the idea of the build on my Malibu. It's a daily rider that will compete in SSNW. I am throwing back some ideas and have heard from each side, but I can get a larger group of ideas online then I can talking to individual people. I would put this in the build log, but I am putting a poll with this, and can get more responses faster with a new thread. This would be a place for some useful information to others as well. There are my 2 areas of thought. I am doing 2 runs of 4/0 wire, and have these 2 possibilities.
1. Run one wire hot (positive) and one ground (negative). I always thought that this would be the proper way to go. Make a complete circuit (modern theory of current flow) of alternator to front battery, through wire to back battery, into the amplifier, into the subwoofer, back to the amplifier, back to the back battery, through the wire to the front battery, and to ground. I never really thought of option 2 seriously until it was brought to my attention today.
2. Run both wires hot (positive) and ground (negative) one in the front and one in the back, using the cars frame to proved a closed circuit. This makes more current flow possible, and does not use the wire as a source of power if the car is off. This provides more power when the car is on and the alternator is running, but less when it is off. Since I would be competing with the car on and obviously driving with it on, this is now also an option.
I am putting a poll in this for popular vote, but the main decision will come with proper explanation of answers. Please provide. Thanks guys!
