Roof Rattles

[LILC509]

I was just called from the shop that my system is being done at. It sounds loud ass hell. But when I turn it up loud when the bass hits, the roof sounds like a tin can. That noise has to go. I was looking into different brands of sound dampening. Has anybody used Dynamat Xtreme or Fat Mat Mega? I used a dynamat in a Chrysler 300 I had only in the trunk and it was great but the price is steep. So any info would help. Also how hard to take the headliner out of a 2007 GMC Yukon XL non denali but with bose? Any info greatly appreciated.

Check your overhead lighting fixture in the rear of the vehicle, I had the same problem, turned out to be the lighting fixture vibrating, solved the problem by pulling the fixture and stuffing memory foam behind it, no more rattling/vibrations.
