I have a second battery in the rear of my X that is just for my system. I was wondering if it is better to run the 1. + wire from the battery up front to + battery in back or to run it from the + alt. to the + battery

Run it from the battery in the front, and use an isolator switch. Then you can choose which battery you want power from.

yea but then how is the battery in back gonna get charged and how am I supposed to use the things I have hooked up to the battery in front.
Here is what happend. I hooked up a 4 channel amp using the + from the battery in back. Now the battery in back keeps draining. Im just wondering what would be the best way to keep it charged, by running it from the battery in front or from that alt. Also would I be better off running a seperate wire from the battery in front to the 4 channel amp, and just to leave the 2nd battery for my sub amp.

From what I understand, if you hook up two batteries in a parallel circuit( + from alt. to front, then to back battery) the front one will recieve all the charge, and the rear will get very little, unless you can isolate where the charge is going.
Part of the problem is that one of the batteries is in the back, using long cables to reach it. If it was underneath the hood, it would be a shorter distance to charge, since there would be almost no power loss in the short cable that would be needed there.

No prob
An isolator alows you to charge one, or both batteries at the same time. It alows you to run amps, lights, winches etc, off a secondary battery independantly, or use both for starting. It uses a little switch that you mount inside the vehicle....

I just got done doing some research on these isolators and im going to get one. Does anyone know what size wire I should be using for all of this?

Ok maybe I should be more specific. What size wire is recomended to run from the battery in the front and from the alt. to this isolator. I will be running 4awg from the isolator to my battery for my stereo.

Dont tell me this. Im going to pick one up tomorrow. Can anyone else confirm or deny this.

Go to a marine supply store to get the parts and ask about running multiple battery setups. Multiple batteries are a must for boating, and so the parts are more common (possibly cheaper, but don't hold me to that), the sales people may even be able to answer your questions.

At least with the brand Guest isolators for marine applications i have never had and problem with battery sizes. Matter of fact i have 3 batteries on one output of the isolator and a single battery on the other output. But like was stated i would talk to the salesman about your application. Here is the link to Guests site on isolators

thanks guys. I picked one up today (actually my friend had one he wasn't using). Now I ran into another problem, this is so much fun isn't it.
I was using 4ga wire for everything, then I ran out.
I got both batteries hooked up to the isolator using 4ga. I was wondering if I could use like 2-3 8ga wires, which I have plenty of, from the alt. to the alt. spot on the battery isolator. would 2 or 3 8ga. wires give me the same output as one 4ga wire?
Like always thanks for all of the help everyone. I would be lost without all of you and your knowledge.
