Focal Beryllium BMW

Ok guys, the amplifierbox is finished. Did some modifications here and there.

Here and older picture of the side.

It’s especially about the front of the the little L-slat.

I have some more join on the side, but it’s better then before. It’s much tighter on the front now.

Pictures of the side.

The grille on top, is the same I used in the front bumper.

Now it’s looks like I wanted it to look.

You won’t see much of the sides directly, but you know there will come a lot of glass on the side….

Here the sides of the box will reflect into, and I think that will give a nice effect.

This is the final result of many many many hours work.

Here you see how I mounted the plexi. I did this in a really simple way.

On the front I screwed the plexi tight with 2 little screws M3.

This plexi must be able to be removed for cleaning or to adjust the amplifier.

I also foresaw the illumination of this thing. I only could do this on the front. So i used a LEDSTRIP.

This doesn’t needs much space, so I managed to build it in quite nicely under the cover.

Here some shots with the blue lighting.

These are made during the daylight. I think most people will see the install in daylight conditions.

This pictures is made at night.

Pictures made through the side

Because I want the people to see the inside of the PPI, I had to screw off the top.There was a little problem though. The cover held the power amps in the cool paste. I managed to make 2 new copper bars that do the same thing.

Milled a little diagonal side on the front.

Here they are mounted. Each bar is tightened with 4 M4 screws.

If you look closely you'll see why I made the side diagonal.

 I glued a piece of self-adhesive vilt on the bottom. I did this to prevent scratches on the plexi and on the paint.

The plexi glass is painted in the same colour as the car. TITANSILVER

The slots I milled into the plexi, don't catch the eye like I planned it. But when the lights are on...that'll change.

Your copper bar is bowed, I can see the arch in it.  It is holding the transistors just to the outside of the screws just fine.  The ones next to them, not so much.  Where the bar is high, it is not doing it's job.  You really need a thicker bar, or an angle instead of a flat bar.

Most amplifiers that use a bar type clamp system have one screw per every pair of transistors.  That amp gets by with the screws that far apart because the metal tabs on the bottom cover are designed to bend a bit when the screws are torqued down.  The flexing allows even pressure to be placed on each transistor.

And I am thank for all the pictures detailing the steps of creation, this is the most pictures ever encountered on a forum thread , but I am appreciative of it though !! Great work, I assume you will answer questions of other members when time allows. KarTuneMan, good to see you are still around , I am just now getting back to being on here on a regular basis. I am a Idiot, good to see you as well!

Thanks, I'm trying to explain everyting so good as I can, together wite some illustrated pictures.
