I had the early 90s 800w version of these. Also had a 2 channel PPI from around the same time. It was about 6"x 6" and it was white with blue and pink designs on it. Also had the splicable power and ground. No terminal to screw into. Holy shit I found a pic of it. It's the little one in this ebay pic.
i have a PPI PC1400 - does like 400w@2 mono. its from like mid-late 90's. id say 98 or so. its chrome and prolly like 14" long - and its powering an e12k flatcone from like 3~5 years ago //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
i just recently sold my memphis belle 16-MB17 4x75@4 + 2x150@4 and it was powering my whole system. prolly from around 98 as well.
im currently running a pair of image dynamics CD2 fulboddy horn loaded compression drivers. still worth well over $200 used - i would also say from about 98 or so. still sound as awesome as evar.

Got a couple old eight tracks in the garage. But I think I still have the underdash 45 player out of a swinger around here somewhere. I think that's the oldest thing I have laying around still. Used to have an alpine cassette changer. Some crack head stole it out of my shop a couple years ago. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
