How to ground my Amp on Yaris Hatchback

[The Architect]

if you want the best ground just run a length of wire from the - batt terminal to the amp, if youre using 4ga. it wont cost very much and youll know for sure.

Thanks RUFFSTUFF, I had a few hundred question marks running across my head when I read that post too.
On the other hand of ovrkill takes the alternator whine out of the sytem then so be it. The more power you have going to the amp, and the crisper your speakers are capable of the better chance you have of hearing alternator whine. So w/ 150 watts going to each of my front B.A. I have a pretty good chance to get the whine if not done properly. Especially at higher volumes.
Kinda getting off topic but grounding the outer connector of each RCA to a random screw that toucches the metal frame of the radio helps. Had that problem w/ an old 2006 pioneer HU, but not my current HU
