Space behind driver seat

Does anyone have any input at all??

Those openings likely serve no specific purpose other than to conserves steel in production. Suggest using seat belt retractor mounts as a ground point.

possible could be vents holes or something used during manufacture to hold the piece....

Thanks guys for inputs.. Have my amps ground to seat bolts, awkward angle for terminal, had to bend...

I was going to suggest the same. It is not smart to bolt anything to a restrain system anchors. They are made with enough tolerance to withstand forces generated in a collision, so taking them off and adding a spacer (terminals) in them may not be wise.

What I would also recommend is that you run a cable from the battery negative terminal and into the cabin to where you have the AMP grounded. I have two amps in my RL and without the direct line from the battery, I had a lot of electric noise.

I have heard good and bad things, running wire from battery - to amps.. Some usually and rule of thumb, correct me if I am wrong. Shortest ground wire as possible, under 15"

Electrical engineers (or electricians) would say it depends on the gauge. This is to keep in mind the resistance for any given gauge of wire and length so you just dont end up burning the wire by overheating it.
