Would you mind sharing where you got the mount for the Focal 3" and tweeter drivers (the MDF-looking piece)? I am considering a component setup but not sure where to source the mounting from.
Also, did you run new wires through the doors or are you splicing into the factory wires somewhere behind the dash to send power to the doors?
He used the mdf to reinforce the bass driver at the bottom of the door. Otherwise, he would be mounting the speaker on the thin door plastic. I think he used the oem plastic oval to mount the mid and tweeter. Nice work.
