Soundproofing Killed My Headlight

I am having someone add sound deadening material to my 2013 in preparation for changing the speakers and adding a sub and external amp, and somewhere along the way my left headlight went out. He accessed the carpet in front and back of the front seats but did not remove the front seats or center console. He did remove the rear seats and rear panels where there is a lot of exposed metal in that back hatch area. Any ideas on where to start looking on where a break may have occurred?
