Has anyone added a powered sub? Any audio techs here?

I picked up the ground in the back of the trunk, left side. There is a factory ground point available right on the floor tucked in the corner. I didn't do anything with forscan. Just wired, set the gain and done. Trunk rattling bass.

Could you send me a pic of your ground point? I think I used the same. Picked up a new amp and same issue. It seems like it happens most frequently on the highway when I'm on cruise or at speed not gassing it.

Hopefully this helps, but the connection is under the plastic in the back corner. I did it when the truck was apart.i don't think you can reach it when everything is in place.

can we use the 12V cigarette plug in the back for power and ground to power an pre amplified 10'' sub ?
