For those interested to have instructions on how to remove the door panel, please refer to the other thread on that. http://www.sgmerc.com/topic/25356-glc-remove-front-internal-door-panel/

After the interior door panel is removed, this is what you have. Notice the empty triangular speaker grille?

Look at the following picture for reference on where are the clips and connection points. This will let you know where to push/pull to release the stock grille as well as where the new rotary tweeters should be installed. The highlights are colour coded to show where the surfaces are mated. Blue to blue, green to green and red to red.

The 3D Rotary Tweeter main housing installed in the position of the former orginial empty speaker grille.

This is the 3D tweeter held up and labeled to show the important connection points. Essentially split into 2 sets: S= Speaker  L=Led.

After connecting to some of the stock door connectors

Now hold up the interior door panel, connect S1 connector to the door panel speaker, plug one of the blue connectors to "5" slot of the DCM. Plug the other blue connector to L2 connector.

Next, you are ready to reinstall the door panel:

- reattach the door latch wire

- thread the door lock knob through the hole in the door panel

- line up all the panel holder 8+1 bits, make sure the top horizontal window edge is "hooked" along the attachment ledge. Start to give firm hard thud using heel of your palms to secure down the door panel to the metal frame. 

- screw in the 2 T30 torx screw into the original holes. 

- switch on your engine and enjoy the fruits of your labour!
