2013 Yukon rear quarter panel flex

[Clay2001]

I have a 2013 Yukon Denali, it’s running 2 Skar EVL 12’s, it was a loaded enclosure from Skar Audio, with a Skar SKv2 1500.1 mono amp, I have sound deadened all doors and but there is no way that I have seen to get to the inside of the quarter panel to try and fix major flexing that is going on, does anyone have any ideas on how to fix it?

You can just change the box position / orientation, fire the subs differently etc. to avoid flex.

 

If your box is setup the best way and you don't want to change it then there is a way to properly unmount any panel of every car, if you don't know how to just look for some video on youtube to show you how, there are plenty of videos, you will find what you need in no time.

I’m not certain, but I believe it is spot welded together

Joe X was referring to the plastic body panels inside, not the metal structural pieces.

Pull the rear cargo panels, it's easier to get to by removing the tire jack and spare tire removal etc etc...

None car audio related, but vehicle related... Can always try a Chilton or Haynes book to see what steps it has for removal of body panels/etc.
