Yea, an isolator is only necessary if you listen to your system with the car off. And, you can run the wires to the extra batteries straight to your alternator if you want.

A couple links to some box builds:

Tahoe Box 1, Tahoe Box 2, Nissan Titan, VW GTI,

Mini-Bump, Hummer H2, Ford F-150

My own car builds (current setup --- under construction):

Overall Thread, Kickpods, Dash, Back Doors

It allows more power to flow...Basically, power goes from your alternator, to your battery, to your amp, to the ground, and back to the battery. Now, we all know running bigger wire allows more power to the amp, but without upgrading the other wires, it's an incomplete upgrade of that circuit. Upgrading it will allow power to flow more freely. All in all a good thing haha

Very easy.

All you need is 10-15 feet of wire and a few ring terminals.

1) Pos Alt to Pos Bat

2) Neg Bat To Ground

3) Alternator/Engine to Ground

No more voltage drops!

And to help with lights dimming, you can upgrade the wiring going to the fuse box as well...that should take care of it.

your alt/engine is grounded already by being bolted down.

the last step of the big 3 is upgrading the battery ground.
