This is project Underdog. A 1992 GMC truck restoration project that my son and I did. It is a 6.5 Turbo Diesel with 300,000 original miles on it. Took about 11 months to complete, now we are installing a custom stereo system with two JL 13tw5's, Focal speakers in the doors, JL HD amps and an Alpine head unit. We did everything except the new glass installation. Its new again. Hope you enjoy the video. Stereo Install: https://www.youtube.com/watch?v=e8Yu-Eh5WDc
