Question

How do I know if the metal is grounded so can ground my amp to it ?isnt all the metal grounded?

Answer 1

yes it is all grounded    just make sure the paint is off when u s***w it down

Answer 2

connect it to the frame of your car. get creative with it. put a connective rings at the end and u can s***w it between your seat and the car( between the frame and the washer/bolt) i have mine under my box, i grinded the paint off  a small section , drilled a lil hole, screwd in my ground, then i put a small tack weld so it never move. if the ground isnt done right ur amp will keep shutting off. so make shur of yourself.

Answer 3

Not all metal is grounded!!!

You would like to find a point in your car that has a good connection to the frame of your car. The lower the resistance the better.

Do not use a section of metal that has only a few spot welds connecting it to a larger section of metal in your car. If you use a spot that is an insufficient ground point the amplifier will try to get ground from other areas like the rca's. This will create engine noise (a whining in your stereo system).

Answer 4

for the most part all the metal is grounded just make sure that you scrap the paint off for a good connection

Answer 5

Basically by "Grounding" you are looking to complete the circuit back to the car battery's negative terminal. You can attach your ground lead to any piece of metal that is some how welded or directly bolted to the steel body of the car. As was stated, you want to make sure you grind/sand down any paint or coating so that you see bare shiney metal to get the best ground possible.

On my car, I removed the rear seat cushion  (had to do it any way to run my wire) and used a large bolt I found under there. I can not stress how important a good solid, clean ground connection is in having a nice sounding system.
