In the meanwhile I made a whole into the doors platework, behind the speaker.
You can see the windowglider. Just nog touching the speaker.

Made some more parts, to fill up the other wholes.


On the background, there's a alu plate of 4mm thick. Very hard and strong.
In the middle you can see 2 Carbonkevlar parts. I made em as thin als possible .
On the foreground you see 4 little rings I made, to screw the doorpanel extra tight.
If you look to the second on the right, there's a little rubber he pasted on. On the place where he screwed it. This to prevent resonance.


On the picture you see a little pole picking out. That's MEGA IMPORTANT.
Behind the speaker, there'll be another screw, so we can attach it even more in the middle.

Everything mounted:




This won't be the end of the door. I has to make some tiny wholes airtight, but that won't go untill the has all the material to fill up the sound.
All I makes, will be filled up with this material. What exactly I going to use, he's not sure. we'ill keep u informed.
As you can see, I putting a lot of work into all this. And more work is coming up so the sound won't be lost...
I think this is a type of work, that is underestimated be many people. But the work will pay of in the end, that's what we are sure of...
