I had an '86 Mazda B2000 extended cab, it was white with dark tinted windows and some nice graphics, it was actually a really nice looking truck back then. Anyway first I put a radio shack tape deck in it rotfl! Then my friend put a CD player and amped his 6x9's in his Escort, so I had to one up him. For the life of me I can't remember what my head unit was, but I bought 1 15inch MTX sub and and Rockford Punch amp. My dad built a ported sub box that took up every inch of the back area that would normally have two fold down seats. I'm sure it was too big for the sub, but my gosh did that thing put out the bass!! I was the envy of my high school as far as bass goes for quite a while.
