Having trouble finding engine block ground for Big 3

[DevonRay]

Doing my first big 3 install myself since it seems pretty easy and not worth the $90 the car audio company quoted me. I have 2/3's of it done and just need to wire the engine block ground to chasis. However I am not super sure where the engine block ground is. I drive a 2012 ram quad cab with a 5.7 hemi in it. Help would be much appreciated. I can try to get some pics up later.

Look around the engine bay. You should be able to see the factory ground wires connecting the chassis to the engine block. It's usually at a lower location.

Follow the negative wire from your battery to the engine. Usually they attach it somewhere by the starter. You can also use one of the bolts that attach the alternator brackets to the engine.
