So I've started to do a stereo build in my Silverado ext cab. This is my first stereo build, so I'm kind of a newbie at it, I'm just learning as I go. It won't be anything spectacular or something you guys haven't seen, I just thought I'd show some people who appreciate what I've been up to. My plan is for 2 12" alpine type r's, speakers, and an amp. I have the speakers and head unit in the car already, so mainly its just the subs and amp, and sometime in the next year I'd like to replace my speakers.
