This is a tiny sound system compared to my 1980's ten speed. It emloyed 2 motorcycle batteries, a car amp, dual tape decks 5 bsnd equalizrr, 2 12 invh subwopfers, 2 5 inch all range, 2 horn speakers, 2 tweeters in a customized ine off light weigjt cabinet made from reinforced foamcore, on a fiberglass one off bike rack. It looked like the front end of a Honda Goldwing from this angle in the photo. Both my wheelchaor and boombox don't weigh even half of that big system.
