I bought an entire Sony system including speakers on clearance from Wal-Mart for about $70 a couple of years ago and it's been on the shelf ever since. I might buy an amp and build a sub-woofer into the back of my center console. I'll probably mount the 4 x 6 speakers in the side kick boards and the 6 x 9's in the rear above the cab corners. That's all months away though.
