Finally got sometime to update this, been meaning to do it for a while.
Focal 100KRS K2 components installed in front doors using 808Mguy’s Speaker Adaptor Rings which I previously used in my e90, HK window trim ordered from BMW and tweaker installed and fitted. Ordered oem speaker connectors to keep it all plug and play so the door guard can be easily removed if necessary.
Used a couple of plastic washers between the door and the adaptor rings to allow for the bolts heads (used to secure the speaker to the adaptor) and used thick weather seal foam to seal the gap up.
Crossover installed to back of door guard, wires run in braided Sleeve to keep it neat.
Skinz wave diffuser foam used to stop sound bouncing around the inside of the door guard, Skinz's sound deading was used on the door (not pictured).
Door guard back in place, HK grill installed
FOCAL 100CA1 installed in the rear doors, aluminum Speaker Adaptor Rings purchase on ebay.
OEM speakers removed, there is more room between the glass and the metal than in the front
OEM underseat Subwoofers replaced for MB Quart QMW200.
OEM Subwoofer enclosures removed, Stereo system has the subwoofer glued into the enclosures so gets a bit messy when removing them with a hot air gun.
Out with the old, you can see the amount of glue used to secure the sub to the enclosure.
Weather seal foam used to make a good seal when the new subs are bolted in.
New sub installed back in the car.
Oem cover back in place.
