I have a Pioneer 3500 in my 91 Troop. It had OE crappy speakers as well to begin with.

The rear speakers were mounted in their stock locations: above the rear doors on either side of the rear dome light. Good position I think, but baaaaad quality sound.

SO...I have stereo and speakers from my previous truck...Pioneer 4" for the front and 6" Fosgates for the rear...the Pioneers went right in...and give a better sounds quality than the previous ones but do not sound as good as they should.

The Fosgates I bought 1" spacers for (the spacers are absolutely neccessary as there's not alot of room behind there. Sounded like a good idea...but ugh...horrible sound. It was unbelievable the difference I heard in the old 95 S-10's doors and now in the Troop. Sigh.

I was building a shelf for the rear compartment, so I decided to just build a "box" for the speakers. It was my first time doing that...came out pretty well but I will do things a little better next time.

The speakers face straight up from the top of the box and that surface is covered in the same carpet as the rest of the shelf, tho it's its own seperate unit that sits directly behind the front seats (rear seats have been completely removed) and it can be moved or taken out completely.

Better sound, better placement and a fun woodworking project.
