Recommendations for a car stereo set-up?

I have 6x9 Kenwoods under the package tray. I held them under it and ran the screws thrugh the tray holes and into the speaker mounting holes. I am ordering a bracket for the dash speaker from a guy on here it allows you to mount 2 3.5 in factory speaker opening. And will be ordering some new kick panels with the speakers grafted in them.
