I'm not saying you have to, I'm just saying it's better in these cars to do it that way. I'm not saying that not doing it you're system isn't going to pound. I never should of even brought it up. This is like which CAI is the best, everyone has their own opinion.

The way you think about this is the way I was taught way back when. I've installed many a stereo system in my day, I helped build a 15,000 watt chevy astro db drag van when db drag first got big. If you look at just about every high powered professional db car out there, they have batteries in the back and the main ground goes directly into the battery.

If you're running a 0/1 gauge ground wire to your chassis, then what size is the stock ground wire from your battery to your chassis? Most people don't realize that it's usually a 8-10 gauge wire. Now how is that 0/1 gauge ground wire being used effectively if the chassis is getting it from a 8-10 gauge wire? It's not, most people don't think to add a seperate ground wire to match what they are using in the back.

For home running to work best, you need to avoid ground loops. Using a side and top post battery works best. Using either the side or top post for stereo only will help unwantted ground loops.

This is the last I want to say on it. Believe me or not, there are a lot of people out there that believe this is the best way also. You don't have to believe me, do some googleing and your find pages about it.

 

yea i did the big 3 0/1 from the alt to the battery, battery to the chassis, chassis to engine block, what did u set up in da db drag van, what numbers you hit
