If the stock tweeters were unplugged, there is a good chance that the p/o changed the stock midrange to a coaxial speaker. You will want to check that and make sure. If there is an aftermarket speaker in there and you connect the tweeters, the impedance will drop and will blow your head unit in time.
Please explain the comment on the tweeters. I kept mine connected, as well. If I need to tear the doors apart again to disconnect, I'll do it, but would like an explanation. Why will less impedance blow a head unit? Right now, they're wired into the connector harness that came with the speakers, not in series.
