Hey I just did mine today I have a 2010 Aveo LT 4 door an there is only 1 screw I had to take off. It was on the door handle the rest was just snap screws I beleave you call them. Ok an I also put 5 1/4 speakers in the door as well the 4 that they say fit to small. You just have to mod the spacer thing and there you go. This is also youtube video I did.https://www.youtube.com/watch?v=TOJgnoohjl0 hey hope it helps.
