I have a 2010 Chevy Equinox LT1, so it doesn't have the upgraded stereo system. I have my amp and two 12" subs from my old Chevy (Colorado) and I was hoping to put those in my Equinox, but it looks like that might not be able to happen. At first I was going to use what I thought was an empty subwoofer cubby in the back until I realized there is an 8" ANC speaker in there, plus I think it would rattle too much anyway. So I will just build a speaker box to fit the subs in the back, so that is not a problem. It is the amp that I am worried about, not sure how to hook that up without replacing the factory stereo head unit.
