I surface mounted my tweeters
Thanks to sjones sharing information I now have 'tweeties' too and let me tell you, they make a great difference. The stock stereo has some bass and lots of mid, but no highs. The JL Audio .75 inch tweeters add sparkle that really brings the sound alive.
I just got done with the installation. It took about 3 hours. I got the door panels off following the instructions to the letter. You need to remove the speaker enclosure from the door and open it. Next, drill a hole in the top and feed the tweeter wire through. Solder the tweeter wires to the speaker leads at the speaker. Seal the hole with hot glue. Put everything together and feed the wire up to the front triangle area where the tweeter will go.
I decided to surface mount the tweeters to the front cover rather than flush mount them. (you must cut a metal bracket behind the plastic cover in order to flush mount them and I don't have the tools or expertise to do a good job of it, so I took the easy way out.
I used hot glue to attach the speaker housing to the plastic cover and drilled a hole through the cover for the wires to exit.
Put it all together, and WOW.. It was definatly worth it.
HOWEVER.. I'd gladly have paid a stereo shop $60 to install them, but on the other hand I'm glad I did it myself and know that nothing got broken or reassembled wrong.
Thanks sjones, and everyone else on this board.
Best wishes
