The amplifier, subwoofer and the mounting board are the primary contributors to additional weight.
I decided that I wanted to achieve a couple of things:
1) relocate the weight to better distribute it
2) design it such that it could be completely removed for track days and service
I kept thinking about where I could place the components and how I could secure things. I started searching the Pelican archives for inspiration.
Lo and behold, I came across this old thread by imcarthur.

He placed his amps in the nose of the car. Great idea!
Post #11 had the inspiration I needed. Brilliant solution.
He used a carriage bolt secured to the spare tire to mount the amp board.
The only flaw I could find in his thinking was he used SAE hardware that meant he had to keep keep a SAE wrench/spanner in the car at all time. That clearly won't do in a German car.
So I visited my local fastener store -- Threads for the South (great place!) and acquired an M12x80mm bolt, nuts and washers.
I found one of these on Amazon so I can just spin it off by hand. No tools required. Just insert the M12 nut in the plastic housing and voila!
FYI... if 9 more people are interested in this idea, you can send me $1 plus shipping costs and you can have your very own.
