I am going for a modified version of what DDassow01 talks about. I have to fix my cut dash first in order to complete it. I have a working AM radio and I'm going to put the radio and new speaker in the dash to return it to 100% working factory configuration. Then, for most of my listening I already have under the seat a bluetooth compatible amp and 4 ea. 6.5 inch round speakers installed in custom wooden boxes. Amp in the middle, and speakers under the seat on driver and passenger side facing forward and up. Sounds like music is coming from everywhere, very solid and clear sound. 8 inch subwoofer in a custom wooden box is sitting in the corner where the jack normally is, and jack is in my toolbox in the bed. No modification to the truck except to run power wires. I thought long about this and went this direction because I didn't want any modern aftermarket junk in the dash (or really anywhere else in the truck) that is just going to quit working after a few months.
