I've got some new speakers to install in my 2014 Silverado Crew Cab. Just curious if anybody here has done this on a late Chevy pickup, and how much of a pain in the ass it is? I've got instructions and wiring isn't a problem, just concerned about getting the door panels off and back on. The "clips" make me nervous.....don't know what to expect. Really hope this ain't a 4-5 hour job.
