Tearing down the rear interior is actually not that bad once you are familiar with it. There are some great YT and pictorial tutorials. I've done it a few times and with that experience i can pull the rear interior in about 15-20 minutes. Once you get to the speakers, It takes just as long, if not longer to maneuver a ratchet under the rear glass to do the actual speaker swap.
