well you overlooked a closer spot. You can use the bolts that hold the seat beltys or back seats themselves as long as the paint is cleaned off and the holes are threaded. If not possible I recommend running 1/0 or larger from a suitable spot to a ground bar that can be mounted closer to the amps. that way you have a commom ground point without the issue of interfence from 2 long runs.
