thanks to the following video and guides I was able to complete this project: Guide: www.corvetteforum.com/forums/c5-general/4415474-finally-a-stereo-head-unit-that-fits-in-a-c5-mostly.html
Video:th-cam.com/video/ndIsXHNpimU/w-d-xo.htmlsi=Oz43-rZ8C1lfyn3q.
so if you see both + my video for details. You should be able to complete this yourself.
Tips: Go to setting/sounds/ Have "Amp" turned on. this is what allows the pac 1 to use the internal amplifier for the subwoofers. Just remember to have the blue cable that comes with the stereo connected to the amp trigger (orange "AMP-CONT") cable from the PAC 1.
