I want to have a special luggage cabin for 207.

There is a 1500 bass in the trunk of my car and it covers all my trunk. I want to make a cabin like the picture for the luggage. Is there a place you know that can do this kind of work in Istanbul / European side? & Nbsp;

If I put 2 20 bass on the right and left side, I think I will get a medium bass sound even if it is not very good quality.
