I remember the crazy **** we used to do when we were teens and 20-somethings back in the 70's and 80's (for me)! I had a huge, heavy pair of 'Technics' 3-way home speakers with 15" woofers that I put in my 1984 VW GTI. I had to lay them down in the rear hatch and fold down the rear seats. Even without an amp, my Pioneer car stereo (25w + 25w) and external EQ drove these things to insane sound pressure levels!
Between our heavy metal doo's and the loud-ass stereo, we thought we could impress the babes! God, I wish I took pictures (of the hair AND the speakers)!
