Front speaker adapters for Citroen C4 II

Adapters for fitting new speakers into your Citroen C4 II (B7). The front door speakers are only needed for pre-facelift models where the original speakers use 3 screws instead of 4 and are meant to be used with 165mm speakers. You also need to pull the speaker wires back through the silicone membrane. Tweeter adapter requires the new tweeter to have a tapped mounting hole in it to secure it in. Then it can be twisted into place like the original assembly. 

Tested with Gladen Alpha 165 G2 with adapters printed in Extrudr ASA
