I know a lot of you guys pull the factory sound system out of your new 17-18s and put in better quality stuff. I'd like to do the same, but it's at the bottom of the priority list. My truck didn't come with a sub from the factory, so just checking to see if anyone has a stock one they'd like to get rid of? I know it's not that great, but it'd definitely be an easy improvement over not having one.
