thanks...got it done. Now can you tell me what wire colors are +/-? left side is blue and red wires but they are not marked in any wayYou disconnect at the tweeter. The wires feeding woofer and tweeter split up and go separate ways somewhere deep in the harness inside the dash - you don't want to go looking for it. Those little grilles in dash corners are very easy to pry out with a thin, small screwdriver. Tweeter is attached to the grille, and wire has enough slack to pull it out a few inches. Then you just disconnect the connector from the tweeter. I suggest fixing the connector to something with a zip tie so it doesn't rattle.
