Interior Popping Noise, Plz help

[sticckz]

I've searched for a solution on Cadillacfaq, and on the forums and cant seem to find one!
I own a 2005, cts, with a sunroof, i recently had a 15' L7 and before that i had two 12' L5's,
i no longer have any sub woofers in my car. i believe this was the cause of my problem, and now i am seeking a solution.
Whenever i go over any little bump, i get the popping, cracking noise from the ceiling.
I also get the noise when i drive up a driveway, it it really annoying!
i am certain it is from the ceiling!
Does anyone know how i can get rid of this noise, or any comments.
perhaps if anyone knows how i can remove the interior ceiling (not sure what its called, ceiling liner?)
any comment would be greatly appreciated!
thank you in advance

Removing the head liner to try to find a finite and intermittent popping noise sounds like an exercise in failure waiting to happen, for a do-it-yourselfer. I wouldn't want you to waste your time, is all I mean. What will you do when you remove the HL and you can't find anything obviously loose? If there's nothing obvious to tighten down you'd be left adding some sound proofing material and probably hunting a new HL. I understand how annoying rattles can be, but chasing down the cause of a rattle can be tough.

After having those huge subs thumping in your vehicle for so long it's no surprise you've developed some rattles. I'm just saying. Perhaps you should install another sub and turn up the volume.

thanks for the comment, i appreciate it.
i will still try to take the HL off, once its off, i will see if there is anything in my power
to lessen the popping noise!
i do not think attempting to solve a problem is a waste of time!
If i find the solution, that'll be great!, however if i don't attempt to fix the problem,
MY subconscious will pester me each time i hear the noise!
i rather try to fix it, and if i can't, then i will proceed to the next step and buying a new hL.
this way, i won't fall under the category of a conscious objector.
i don't like leaving anything that needs to be fixed, unfixed
Putting another sub will not fix the problem, but rather it will only hide it.
when something falls in my kitchen, i don't toss it under the refrigerator!
if i were to put subs again it will only hide to noise, not fix it
i find it to be a similar principle!
AVOIDING THE ISSUE!

The sub comment was a joke. I think you missed it, and you seem like a pretty serious person.

After removing the HL try having someone drive the vehicle while you ride along listening and looking for the cause of the noise. If you can't re-create the noise with the HL off then perhaps the cause of the noise is within the HL itself. Best of luck and let us know what you find.
