Thanks Bjcsc,
I was beginning to think no one cares about 'old geezers' like me and our ancient automobiles' audio problems. Since the failure of my Clarion amp/equalizer experiment, I've tried one of those small, amplified computer-walkman speaker systems. It uses one 5 inch cube woofer/amp unit wired to two 4"x 5" L and R flat panel tweeters. But what sounds OK indoors doesn't have enough power and bass to work in my 220S.
Next, I tried a pair of 2 way 'cube' speakers, wired to a fairly powerfull mid '80s JVC boombox/equalizer combo just to test various speaker locations, including the footwells, rear shelf and under the front seats. With the JVCs' power and various equalizer settings, all of the tested speaker locations sounded pretty good. I still have an, untested, Blaupunkt amp/equalizer to try out, but if that turns out to be a dud, I'll probably have to go with this 'Pyramid' unit, you suggested. At about $20, the price is cheap enough! Thanks again.

Happy Motoring, Mark
