Thanks to RB for his idea to strip the factory mid ranges...
Ok so I took my time last night to:
remove the factory dash mids,
Using a soldering gun I heated up the solder and simply pulled the factory wire harness off which left me with nice solder covered wire ends,
remove the magnet off the black plastic basket using a drywall trawl and then dremel off 3 "legs" of the basket (leaving the leg with resistor clip),
then cut off speaker cone and cleaned up surface where old cone adhered to rim (so now I have a naked black ring essentially to let my new speakers sit in),
cut the new Fountek speakers from square metal to round and press fit into naked ring (lining up new + & - terminals close to where the original position is). I needed NO adhesive at all since when I press fit my cut metal edges into plastic it was catching and holding inside the black plastic ring extremely well. So a test fit was all that was needed. I couldn't remove them easily (tho I could).
Soldered on the wires (first time soldering and it's an art form I found out),
Sat back and enjoyed the perfectly factory looking speakers again.
Installed and have been enjoying the cleaner sounds. I have always thought the tweeters and mid range speakers have sounded muddled, and after installing these Fountek's I sooooo agree that the pillows have been removed. Now I'm curious how new JL C2 600 tweeters will also brighten up the sounds.
