Alright, cool. Got them out and put in my components. I used a drywall circle cutter bit to cut out a hole for the tweeters in the fabric-covered metal piece right to the side of the speaker grill. It worked on one side, but not so well on the other. I think I'm going to recover the metal panels on the doors. At least they're done. I was getting ticked off with them. I broke the passenger grill off and tried putting it back on with some silicone caulking b/c I didn't have enythig else and thought it would work. Well, it didn't, and I threw the bottle and it splattered all over the driveway. But once I recover them, maybe in black, they'll look better.
Thanks for your help!
