Last night, I welded in some fish plates on the rear frame rails, but tonight, I took a break from working on the chassis, and began kicking around some ideas on how to mount the 6-1/2" speakers up front. Space is extremely tight, especially on the passenger side. Cutting up my door panels was not an option. I came up with this idea, build speaker cans out of 6" PVC fittings. The wall thickness wasn't quite meaty enough for the speaker screws to bite into, so I had to glue some pieces of PVC pipe to create enough meat to support the screws. To improve the sound, I'll put some poly fill inside them. Once I roll a couple coats of black Monstaliner on them, I think they'll look pretty good.
