I want to hook up my dry cell in the front my my car to the one in the rear. What do I need to accomlish this? Do I just run the power cable from power to power and ground the batteries or do I need some thing in the middle of both batteries. The back battery is going to a 5fard cap and then I am going to take 0ga to the distro and out to the two amps. Please let me know what I should do.

Thanks

Running your battery to the rear is fairly simple. First thing......a BIG ASSED fused for under the hood, on the wire going to the second battery. If you are planning on running the stereo LOUD, for long periods of time, you might want an isolator instead of the fuse. That way you can still crank over the beast when your done jamming. You dont need to run ground. Mount the rear battery securly, and get the ground from a clean SOLID piece of metal. If you use the rite kind of power cell in the trunk area, you won't need a cap. ( www.kinetikaudio.com ) made for car stereo. As far as the 0ga. overkill......looks good, but its really too much. The distances your current has to travel don't justify the cost of the cable..........remeber....just a suggestion

Cool man thanks. I am running two Optima dry cells I am going to run a 300Amp Wafer fuse to the back battery. I found this h-0 something site on here that somebody told me to go to and when I put in my distance and rms settings and 0 is what it told me to run for the distance. Like I said man small systms I never had a problems with but, since we have started are shop and I have upgraded my system I never had to run all this crazy stuff. So, should I keep the 0 running since I have it. Let me know thanks

If 0 gauge is all you have then go ahead and use it, why waste mony on more wire. I am only running one 10 inch sub on a 600 watt amp and have 0 gauge ran to the back, because that is all i had, plus when people see it they are like "whoa" that is some big ass wire. Plus i have plenty of room for expansion if i want to get crazy.

Optima = same as everyone else Dual Batteries -- posted image.

Just go buy a deep cycle battery for a second battery.

People think that optima batteries are something special, but they really arn't. The "dry" cell battery, also known as the gell cell battery, has been around for years. It's just now being brought into the light for these "kids" that have to have the brand name to be cool.

Fuse the second battery at the back, this is a must.

why at the back? SHouldn't it be fused as close to the pole on the front battery as possible? Kind of like when wiring an amp?

Think about it, why would one normally fuse up front, to keep the vehicle from catching fire in the event of a short circuit, correct? So now he has a battery in the back, what keeps it from starting a fire in the same fashion if it too is not fused within 18" on the run to the front of the vehicle, thus two fuses, one at the front and one at the back.

I would say the fuse at the back would be the fuse headed toward the dist. block or the amp or whatever your powering.
