What are these 2 mysterious holes under/behind drivers seat? Looks like a good grounding location for amp.
Cannot find anywhere online to find it out. I was thinking of moving ground to this location using self tap bolt..

Does anyone have any input at all??

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"
