I'm an idiot. The tweeters are fine. I turned the radio off and disconnected everything as soon as something went wrong. The change in sound was due to a mid dying. Don't ask me how I messed that up, or why I thought I had a dmm on the wire for the tweeter, when it was one for the mid, either..., cuz Idk. Lol, I hooked it all back up for a quick listen, and the other mid went out. Both tweeters were playing just fine, though. Anyways, my bad. Thank you for the offers, and advice, guys.
