Here you can see how I mounted the cover of the speakers without seeing anything of it.
On the backside I screwed 4 aluminum plates, and when you look closely , you'll see a little pin (3mm) on your far right.





The plate is screwed tight with the same screwes the speakers are tightened with. I took about 4 to make it tight enough.
Where the little pin sits, I drew a hole, so the plate is tightened as well.



Because on the backside I’ve got 4 plates standing, I needed to mill these out.





Once I had this I could fit the plate. The plate will be inserted.




On the bottom you can see how it fits, and on top you’ll see the rings of the speakers mounted, and so you won’t see anything of the rest, simple.





The the time had come to provide everything with a layer of carbon fiber.



Provided it with a couple of layer of epoxy.

Being clumsy. I forgot to put hardener with the epoxy. I washed everything with aceton, and did it again. This time with hardener.

In the meanwhile, I have sent the Soundstream amplifiers to England.

I am confident in what Gordon is doing with the amplifiers.
These are some pictures he sent me.

This is what happened with the Soundstream amps.



Preamp chips upgraded to give better dynamics and detail. The TL074 parts were a good chip back in the 70's but the new parts now are quieter and better sounding.
New caps to give more stable power supply rails and more stable imaging.
Mica sheets conduct heat better than polyamide sheet so the bias is stable.
Bias sensor moved so bias is stable at all temperatures and loads.
HP / HC Switch removed as it's unreliable. Stereo / mono / mixed switch replaced with a new part as it had been pulled apart and not reassembled tightly - risk of a bad connection.

i’ve managed to cover the doorpanels, and it worked out fine.





the carbon fiber panel where the speakers will get into, is about 90 procent finished. I need to sand and polish it a bit more for a deeper shine.










Bassreflex is also finished. As you can see I sprayed the middle piece in the same color as the moldings in the car. So I have a nice contrast and still, everything blends in nice with each other.









I need to cover the middle piece of the door, and after that, I can start mounting everything.

Seriously. I'm speechless with regards to the quality level of this fabrication!
