I'm currently running a Soundstream D200II circa 1991ish for my front stage. Also have the matching D100II and D60II in my closet. They all work flawlessly.
Got an original soundstream reference SS10 Sub from a 1993ish install hanging around too. It still works fine as well.
Oh, forgot about the Kenwood KRC-930 Dead Head HU from around 1992, it too still works fine. Got the matching 10 disk changer too //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Edit: Just remembered the 2nd gen Punch 150 circa 1990 or so. Snagged it out of a car I was transporting for an auto wholesaler, in exchange for my services. The same car had an old school Nakamichi 4 x 35 watt amp... Got that one too //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
