Ground in a C5
Where is the best place to ground an amp in the back of a C5? Its a coupe and the amp (Alpine PDX-5) will be mounted on the back wall above the center compartment.

There is a tendency to pick up noise by running a ground to your battery vs. a chassis ground, plus it not all that safe. Where did you get your information from? Also, why are you using 0 gauge wire for your C6 install, are you planning to Arc Weld?

I may be, but I've been installing car audio for 25 years now, and I've never, not once seen anyone ground back to the battery. There must be a reason for that, beyond safety...

Just think about it, the frame is like a big battery negative terminal its just a path to get back to the battery but the steel is high in resistance and has many impurities, an oxygen free cable going back is the best solution in some cars. Running a wire directly back to the battery can not possibly introduce noise by itself, unless your RCAs are right next to it, but again you'd have that same problem with the power wire.

I've seen tons of installers "beef up" the ground by running another separate ground from the battery to the chassis, thus improving the chassis ground.
Who knows, maybe it's the way to go, it's just not common...
There must be a reason that amp kits only have a positive terminal connector, and not a negative..... Come to think of it, I've never seen a negative terminal connector....

Cheap way to sell the kits. Most DIY people will just ground to the frame. Also notice how the parts that come with these kits are also not top end parts?
The best way for the purest source for power is the source for power!
GM could of added the "Big 3" to our cars to eliminate lots of electrical issues but it saved them money by not doing so and that is the same reason why AMP kits dont have grounds either!

I installed one on each side, so that each amp can ground directly to the frame.
Later,
