The Blaupunkt one was like a 5-band with some crazy round sliders or something, you worked the eq with your thumb I think; video game style... I can see it, but I don't remeber much about it.That third one down looks like the first head unit I purchased for my first car.
I later added 2 Alphasonik pma(or ma)2100's. One powered the Pioneer 6903 6x9's with the white cones and the other powered 2 clear poly coned Alphalab 10" subs which I believe were made by MTX(Mitek)
My next head unit was a Kenwood 999....I would love to have one of those again.
Does anyone remember the Blaupunkt stalk mounted equalizers? Clarion also had one that looked like the stick from a fighter jet.
That Clarion eq was fully digital, spectrum analyzer, crossover, memories... I remember that one well... it was hideous!! I remember some guy had two of them in his Jeep... why I don't know!
Those Pioneer cassette decks had the trim ring around the knobs that lit up... that was COOL!! If you didn't have one of those you were out!!!
