My first attempt was in my 70 Buick GS Stage 1. A pioneer Supertuner II twin shaft. A set of pioneer 6x9s in the back deck. and a pair of Jet Sound 6 1/2 in the doors.
My next car was a 75 Buick Century Indy Pace car. A cheap small chassis twin shaft. I purchased for IIRC like $60. at a Car audio tent sale. I think I just used the stock speakers.
My third attempt was one of the best, yeah right. 1970 GTO. The same twin shaft out of the pace car. would fit in the dash of the GTO. so I put it in the glove box. Along with a $19.95 booster/EQ. on top. with a set of Kenwood 6x9s in the deck. I remember one of the channels going out on the booster so I wired the speakers to one remaining channel.
The time period was 1982-1985.

What horrors did you create when you first got into car audio.
