Frame grounds are fine if you have a solid frame. Unibody car should be grounded front battery to rear battery.

Now thats overkill, u dont need the 4 gauge from amp to box

and i must have missed what kind of car you have??I have an explorer with 4 runs and it was less then 75feet, but if your gonna be wiring batts, doing big 3, etc.. then I would shoot for the 75-80ft range - 11-08-2012garretttt4Re: 4500 watts

You don't. Multiple runs to the back is only really useful in DB Drag Street class or similar where you are limited to only what's under the hood.

A very safe rule of thumb is 1 additional battery per 1000W of amp power. You can likely get away with less depending on your listening habits, but you can do a lot if you stick to that. - 11-08-2012garretttt4Re: 4500 watts
