I have two 6" Kenwood KFC-1677s that someone gave me for free. I would really like to install them but my issue is I cannot get the screw holes on the bracket to line up with the holes on the speaker it's self. Does a 6.5" fit w/o modification to the bracket or am I missing something? I'm sorry if this has been covered before but I didn't see anything that talked about fitting speakers to the brackets. I thought I'd ask here before I took the bracket to an audio store and asked them to show me something that would fit.
