Dan, see the 2nd and 3rd to last pics in the very first post.

PBSun cut the plastic frame off the OEM speaker. It has the oddball 3-hole mounting system that BMW uses. Then he screwed his speakers to the plastic frame. The gap all around the speaker is because he used 5 1/4 inch speakers.

I would think that the 6 1/2 inch Infinity 6022si's would drop right in with no gap. Use silicone to seal the bracket to the speaker all the way around. If the fit is too tight, I'm sure you can use the plastic basket as the mount like I did.

I think the bracket from the original speakers is a better solution. There was a little bit of slop in the fit to the basket, but the speaker bracket fits down inside the lip of the basket, so the bracket is a hair smaller than the basket and the fit might be perfect.

Good luck.

thanks, awesome. As long as its just modifying the plastic bracket from the old speaker and a little solder, it should be no big deal. Now - the question is do I want to go for the infinitys that I know will fit....or go for something with a little more low end punch for around the same price? I'll probably stick with the infinitys if theyre an improvement over stock, but since I have no plans to upgrade this further, some 6.5" subs in the rear would be appealing.

I would modify the baskets rather than mount the speakers to your parcel tray. I thought it might sag overtime so I wanted the basket to support as much as possible. Its actually a snug fit.

Here is what I ended up with for the 60.9CS woofer. Don't worry about messing them up, a new set is like 20 bucks, and yes, it took me two tries of experimenting. You can cut the entire basket off though and just use the ring as a mount. As I said I didnt like this since it left the speaker hanging on the parcel tray.

old thread, but very helpful. one of my rear speakers blew and so i am replacing them. one thing that i wonder about is why the rear speakers are not in a sealed enclosure? as you can see from the pic in the post right above, the "basket" that the speaker sits in has like a grate at the bottom of it that is open to the trunk. perhaps the stock speakers are designed to be "free air"? its been my experience that just about all speakers sound better when in a sealed enclosure.. even if its a tiny one. anyone know what the deal is?

those are the same kappa's that I used - or at least they look the same. Mine fit without modifying the cup. However, I used one of the grill plates from the box to mount it down to and now it bounces off the grille when installed. I need to go back out and figure how to adapt it to the cup without the grille-ring so it sits lower. It might not fit by the time I figure that out..

EDIT: Confirmed. I pulled the parcel shelf and tried to sink them into the cups. They bottomed out. I had to cut the cups up and gorrila glue them to the cups before installing.

Here's a DIY for coupes fitting 6.5 Infinity's in the rear deck. I kept my baskets as well.

OP, nice work on fitting the speakers!

Has anyone found rear deck speaker adapters for 6.5" speakers in the US

I have reviewed the solutions previously mentioned and would like to make use of purpose-made adapters but the only source still appears to be the UK with a cost with shipping of $30. I would like to cut the basket off of the old speakers, but the previous owner only left one behind. The use of MDF or plywood and black paint appears to be the only option left for a clean look.

Has anyone found another option yet?
