So with my title I am looking to upgrade the front speakers while i have the truck apart and add some into the rear panels since it is ext cab. This guy was able to fit 6.5" speakers by making his own brackets. Anyone done this before or understand what he did or are you on here and can you take better pictures? The rear IMO could have been done better so not justifying the credibility, just curious how to fit larger speakers up front in the dash
