i know this is basically personal opinion, but thats ok, i have read enough on this site to enjoy all your opinions, haha, its a joke, dont hate me, anyway, im tryin to decide where to ground my amps, right now i have them grounded to the seat bolts but i have heard this isnt the best way, so i got to looking and either i can drill a hole and bolt it on its own right to the sheet metal, or drill a hole and go to the actual frame, what do you all think would be best??
Fine a spot on the inside that you can access from the bottom of your car...then drill a hole and use a bolt and nut. And like fstrfvo said....sand down to bare metal
If you are motivated enough, go ahead and bolt it to the frame! With proper metal preperation of course, followed up by some spray undercoating. Then ground your battery to the frame also! Thats an EXCELLENT grounding method, but the shettmetal will work fine also.
