Yeah, my buddy had Orion and they rocked and so did the amps, MTX was big, and I had 2 x 10'' by cerwin vega they sounded pretty good. Another big name back then was PYLE. I even had 2 super pro plus 10'' woofers made by pyramid and believe it or not they actually beat really nice. For some reason 15's were much more popular then than they are today too. I even knew a few guys that had 18's. Also, the equalizers that were attached under the radio as a separate unit were big i have one here made by sherwood. Rockford lost popularity once they went big with best buy and circuit city etc , their amps began to **** and then their woofers followed. I would still like to have some of that old stuff for some reason, lol. You sound like youre from the 90s, if so , do you remember when JVC was a big name? How about Blaupunkt?
speaking of 15'' I searched old school rf and this came up:

I had an old Rockford Punch 1500 last year but it wasn't putting out the wattage that it claimed so I sold it to a friend for dirt cheap and it later died on him. It was a beast and worth some serious money if it still worked.
