I didn“t find any inspiration directly to this kind of build.
Just had to get a solution for my install and came up with this one and i fell for it

And it is like nothing i seen before so just another reason to try it out.
The box will be installed in the same vehicle (Mercedes A160) and port will be firing backwards to start and then i will try facing it forwards.
The idea is to build up a wall behind the port when firing forward and se how it works out.
Port will be bolted down in the box by lowering t-nuts into the bo so i can choose change direction of the port and easy dismount it for modification

On monday or tuesday i will make next upgrade since my grinder gave up today
