I just recently installed some alpine tweeters in my LX and thought it was going to be a backbreaker but before i did that i checked in with a car audio shop. They told me that they would have to remove the whole dashboard to get to the tweeters and wires or they could just make cut a hole where my side mirrors were which would cost me about $100+. Thank God I decided to do it myself because there was only a few panels that had to be removed to get to the wires and the tweeters just popped off.
