6.5" speaker adapter for Beat PP1 kei car

thingiverse

Because the beat's stock speakers have adapter rings that are integral to the drivers themselves and because I didn't want to go drilling holes in my car, I designed an adapter to fit perfectly in the spot left by the old speakers. Note the 60-degree angle under each of the screw mounting bosses, necessary to clear the screw grommets mounted in the door panels. Included is also a 0.9mm spacer shim. The hardware for mounting the adapter to the door is the stock speaker hardware, and you can use #8 or M3.6-M4 hardware to mount the speaker to the adapter. Note if you own a beat, do NOT buy the Polk MM6502 as shown here. these speakers are too deep to fit without modifying the door card
