My Burmester upgrade process
#126
That looks fantastic, custom and clean. So did your installer calculate the volume of the spare tire area to see if it would be a good match for the 10w7, or just give it a whirl and see how it sounds? I like the idea of not loosing trunk space, which I did somewhat with my current w3 box.
Where is the main battery in the 63? My 550 main battery is in that floor pan so that would be a problem if I were to attempt a floor install.

The main battery is in the beauty cover behind the back seat. So you could use the space the 550 has there.
