6x9 speakers not fitting.

@ AIV, you saying your Polks just dropped in?

Mounting from below is possible, but that drops the speaker way below. Obviously the package tray is designed to allow a 6x9 to drop in from the top and be supported.. Also I have 3 speaker holes for whatever reason.

I was hoping to be able to mount the speaker grill ontop and let it hold the tray in place. Might need some 2in screws to make it all work. Will mess around today and see what happens.

thanks for all the ideas.
