Speaker Replacement
 

Has anyone had any luck with replacing their car speakers with after market ones?

I'm trying to replace mine and I have all the components ready except the speaker adaptor to connect to the existing wiring.

Has anyone done this before and know of a good supplier of such parts?

I've so far bought 2 different types of adaptors, both purporting to be the correct adaptors but are decidedly not.

I've added a couple of pics of the connector in question.
