I'm back with my dual 3.5" speaker brackets

That is a perfect example of a typical installation. The radio and A/C-heater control switch are usually the only things in close proximity that you have to negotiate around. Fortunately, the two that I have installed with my son were done during a complete breakdown of the dash, so there wasn't anything in the way.

The speakers are first mounted to the bracket, then you slip everything up into place and attach to the dash using the original speaker mounting screws. Simple, huh?
