Coupla questions for y'all...

1)Hoes does one remove the plastic grill covering the front door speakers? It doesn't look like it pry's off.

2)How big a speaker can i fit in the rear deck? I'm thinking a 6x9 is the largest. How does one make a custom bracket to hold said speakers? There doesn't seem to be much room.

3)How does one get the front panel where all the HVAC controls are located completely off? I know to disconnect the knobs and clock, but there is like a little tray that holds the control assemblies in the dash that won't come out. BTW, i'm trying to get to the preout on my radio.
