Got mine today. I will put them on the shelf and wait for winter to install another amp and the speakers. to those of you that picked these up keep us posted on any mount changes you make. I agree they are heavy speakers for a single mount and with the issues posted I am going to try and find a way to make them a little more secure. A quick idea I had was to get longer bolts and put a nylock on but I don't think there is room.
