Are all seatbelts connected to the car frame?

Question

I'm trying to ground an amp and the seat belt bolt seems like a good solution since it obviously has to be connected to a strong metal structure. (Like maybe the frame of a car?)

Answer 1

your seat belts are not directly bolted to the frame.... but all cabs are grounded to the frames by way of ground straps so....... electrically speaking yep......Your Grounded.......Daryl

Answer 2

yes they are dont do a thing to a seat belt  you mite do sum harm if you if you wont to ground do it on the sub frame or go to      the the battery to ground

Answer 3

Usually not, instead they go to a reinforced area of the floor panels, in fact I have never yet encountered a vehicle where the seat belts were attratched directly to the frame and that's a lot of cars and trucks.

The body will be grounded to the frame, sometimes this ground is corroded but it's probably good to go, if you take out a seat belt bolt to put on a ground wire, make sure you tighten the seat belt bolt back as tight as it was before.
