My first was a majestik amp on two kenwood house speakers in the trunk of an 81 toy corrolla with phillips 6x9's in the rear deck, the mags on those 6x9's were 75 ounces apiece. With coustic 4 1/2's in the kicks.
First system was 2 15" MTX Terminators in the box that had the built in midrange and horn tweeters. Fuck yeah! Had it in the backseat of my '83 Escort Pony. This was 1988 mind you....
