Mach 460 Tweeter swap

In my 2002 Saleen, I'm about to replace the entire Mach system (Infinity, JL and Alpine stuff), and I'd like to mount aftermarket tweeters in the Mach tweeter housing. Is there an easy way to access it or remove the front cover? I'm afraid if I try and pry with a screwdriver, I'll snap something.

Any advise/tips?
