It looks like you're grounding the amp on one of those child seat bolts, is that right?
Also, I broke my drivers door trim trying to rip the bottom part out without taking off the seatbelt. From the exterior of the panel it didn't look like it went all the way around the bolt. But anyway, I was told that the seatbelt bolt is some kinda tension-blah-blah one-time only thing, and taking it apart is a big insurance risk if I don't get it fixed at the dealership and get in an accident I might void my insurance, some safety thing, am I hearing wrong? How did you handle it?
