Any recommendations for grounding points for a amp mounted under the driver's side seat?

Thanks!

 

you could pop out the center console and use one of the screws mounted to the chassis under there. pull out the little piece of felt from the rear cupholder and unscrew the screw then carefully pull the console up untill it pops off. might take a little force in the front because there are two plugs holding it down. once you remove the console you will see a few different options there. hope this helps

 

um one of the seats mount bolts........

 

^that works, too lol.
