I always thought that it was run to the alternator.

yes its possible, just run some 4ga up to the alty...
make sure you get a battery that doesnt emitt fumes when it charges and such, otherwise you will die. the way around that is to make an enclousure for it and vent it to the exterior.

Whoa there guys. You need a battery isolator ($100+) to be able to charge two batteries, you can't just hook them up together.

Why do you want two batteries anyway? It's just a band aid for not having a large enough alternator.

i dont think that my stock battery can handle almost 2000 watts. and i didnt think there was anything else i could do if u have suggestions im open for them. thanks

Ok first, are you talking about bumping with the car on or off?

The battery doesn't (shouldn't!) do a damn thing while the car is on. What you need is a larger alternator. The battery can only supply ~12.5v, when you are is on the alternator provides ~14.4.

Now, with the car off - you'll drain the stock battery to the point where it won't start the car in about 5 mins. Two Optima Yellow Tops only gives you about 45 mins. Forget running that rig with the car off.
