Wiring Audio System Separate from car electrical?

[CplCuddles]

Hey guys, I am getting a HO alt soon and I am wondering multiple things. 1st, Can I add in my HO with the stock? I figure no point in junking my stock alt if it helps the system. 2nd The real question, If I can indeed hookup both, Could I run my stock JUST to my vehicle and run my HO dedicated to the audio system? Then I wouldn't have to worry about my front battery dying or the vehicle electrical straining because of my audio system. Here is a crude drawing of what I am wanting to do.

Lit, would you advise hooking it up separate or just hooking it into the main electrical system?

As long as you have at least minimal battery in the rear... your front battery would never die while driving..

Battery is too far away= resistance is much higher in that area, therefore, all power from both alternators would be consumed because they are of higher voltage 1st.
