Go buy a user book. I have a 2001 impala and all chevy cars I have seen are set up the same way. There are many screws and panels you must remove. If it has the covers built into the deck, you need to get all the screws/bolts out (which I had to do) and pull off the deck. You will probably also have to take out the backseat which isin't too hard when you have the book. Just find a factory book for your car, it should of came with one. It will really help you alot, but for all the work be sure they are some good deck speakers!
