Audi B5 S4 Front Speaker Adapter for 5-1/4" Kicker Speakers

thingiverse

Modified fergusykes adapter to be able to be used with my Kicker 46CSC54 speakers, linked here: https://www.bestbuy.com/site/kicker-cs-series-5-1-4-2-way-car-speakers-with-polypropylene-cones-pair-yellow-black/6333350.p?skuId=6333350 I believe the original adapter was designed for a 4" speaker, but the kickers are 5-1/4". They fit pretty well, but the driver side was a little finicky to get one and doesn't sit perfectly flush. The original file included a ring to add TPU or silicone to prevent rattling, which I didn't go with and it sounds perfectly fine. I included the inventor file, as-well as the original author did so you can modify to your speaker bolt pattern. Used the original bolts to mount it to the car, and used M4 machine screws with locknut washers to secure the speaker to the mount. I believe they were M4-25.
