Finished Left Door Speaker box mod
 

Well finished the mod on door 1.

Used nokia door box, cut down and fiberglassed, epoxied, and hotglued in 6.5 inch adaptor ring for a mitshbushi because shape was similiar. I had some extra fat mat given to me so applied that around box and few pieces inside. Used a hole saw to open the back into door cavity, speaker is designed for an infinte baffle. So here is a pic.http://986forum.com/forums/uploads02/pic11523307026.jpg

Hey, I wouldn't go so far as to call that infinite or open baffle. Looks like you barely have more port area than the speakers surface area. This might cause some unwanted characteristics in the sound.

Open it up as much as you can, just make sure the front and rear wave from the speaker are separated as much as possible.

Its more open than it appears, can’t cut any more holes because the way the shape of the speaker box is, will cause structural weakness. I am pluging the front port and have a wave mat that goes on door behind the enclosure. Maybe infinite baffle is incorrect term. The point is the holes go into the door cavity.

I am following the 6.5” diy mod another forum member did in concept. I have much more air space opened up than in that diy picture. Not sure how to link back though.
