If it's a big existing ground it could be fine. You're just making a connection to the chassis so if the bolt is big enough to accept your wire and associated terminal, it should be fine.
Try to use factory grounds if one is available. If not make sure all paint is removed in the area of your ground, otherwise you don't have one, or you have a poor one at best.
I did vinyl and noico sound deadening in my 1966 Mustang. It's still an ongoing project but it definitely sounds and feels more solid. I haven't had glass in it since we did the floor, roof, and side panels but I already feel it was worth it. No rattles from the sub either and in a car that is...
As long as you're uniform it doesn't matter, if you have one side swapped you'll be running the speakers in opposite directions and basically cancelling them out.

Table is installed, and while I didn't take pics because it's freezing and was outside from 2 to 8 yesterday washing and installing, her kicker key is in. It's set up bi-amp running only the fronts and has done an amazing job making the system more listenable.
Yeah, we'll definitely go back since we couldn't see anything! Fun ride though. Got to use the hill descent feature going back down and it was nice, stayed in 4a the whole time, didn't need anything else.
Took up trip up FSR630 to Lake Conasuaga saturday. Was too foggy to see anything but it was really more a trip to get off-road and test her out. Got absolutely filthy but a couple hours with the pressure washer and she was fine.
I installed ours last night. Front channels only, bi amped. Mine is run with a power wire to the battery and using a factory ground under the hood. Once I realized I needed to fade forward so the stupid rears wouldn’t ruin the test the auto setup ran perfect.
fyi to anyone running bi amp with...
I’ll check with a magnet but by weight I’d say it’s steel.
Used it this weekend for lunch on the trail and it worked great.
it does rattle off-road but then so does a lot of stuff in the truck.
We came up to our vacation house in north Georgia so we could enjoy some off-road action. I used Gaia to make the path, using forest service road 630 to the lake, and then conasuaga lake road out.
it’s been raining from the tropical storm so not a great day, as we got higher it got foggier and...
