I can see where having speakers of the wrong ohm rating would mess this
up . I believe there is a inline capacitor some where that acts a high pass
filter to the doors not sure anymore.
You could try running one speaker at a time to see if that makes any difference.
(either the door or floor)

Hi mate, thanks for the reply.

The speakers I have purchased are listed as plug and play for my current gen and audio config. I'm going to reach out to them later today and see if they have had any other customers with similar issues.

Thank-you for the links and information I'm going to try and look into this, the new speakers (tweeter) did come with some sort of capacitor/electronics box that must sits in-line between the speaker and the tweeter which I presume has something to do with levelling the resistance to what's expected but cant be sure.
