i just put infinity 5x7's in my svt(rear)they fit right in just fine,but all of the bolt holes didn't line up..i just screwed a self threading screw in the holes that didn't match up(very easy to screw into the thin inner panel)and they work just fine...a little more work,but well worth it and easy to do..they sound 100 times better than the pathetic stock speakers..and best of all i got the infinity's on ebay for $20...
