I read the sticky on stereos here but it is for 2003 and up I have an 02 and want to add an amp and sub to the factory stereo because i want to keep the onstar. where does a guy look to see if I have a factory amp?
Just get a Pac AEM-GM24 and it plugs int the factory harnes and gives you a RCA out with a remote power wire for the sub. It works way better that a LO converter. I know I had both. This is what I have know . Subthump makes a under seat dual 10 inch for crew cabs. It fits nice and pounds well.
