Thanks for the info. I'm getting a rattle from my dome light after installing a 12' sub too.
How difficult was it to remove the dome light? I'm debating whether of not I can do this myself or taking it to a professional. I was even thinking of purchasing some dynamat and taking it to a dealership to see if they could install some in the dome light. Does the dome light pop out without removing any of the roof vinyl?
Any info would help.
