So I Also am wiring in a sub for my Ram 50 2G , I have quickly drawn up a diagram of how I think it should work in paint, but before I start knifing my factory grommets I wanted to make sure that I am doing this right. There is a grommet that leads into the firewall with a bundle of wires tightly wrapped up, I wanted to make a small cut above those wires and feed my 12V though into the dash. Is this the best way, the grommet i am looking at is directly behind the battery located on the firewall.

Thanks in Advance
