RAWK!!! We did the same. The slower the better!
My 2 favorite worst systems were...
1) My Sears brand (supposedly rebranded Fisher) all-in-one with AM/FM, turntable, cassette, and 8-track player/*recorder*. (Never in my life have I seen a blank 8-track tape, but if I had, I'm one of the few people in the world who'd have been able to do something with it!) After most of junior-high and all of high-school with this rig, I got a JVC CD player, opened up the back of the Sears, and jacked it right into the guts of the system!
2) Sometime in junior-high, my sister and I pooled our lawn mowing and babysitting money and split the price of a little AM/FM/cassette boombox. I can't remember the brand, but the "woofers" were rocking 3.5" drivers (paper, I'd wager). I'm not sure how the "loudness" button even did anything with those. The best part is that the cassette transport was actually a portable walkman-style player that had its own battery compartment and headphone jack and *docked* with the main unit. I'm sure you can guess how ugly the fights got over who got to use it.
