As for where to place the DB20, that's still up in the air too. The previous picture was just to test power. Italian cars are not know for their robustness, well robust anything (except maybe the engine ?. But she powered up with the car on and transmitted.
I have a cupholder with bracket but it's about an inch too tall, well, probably 2 inches to provide some air flow.
I feel I'm getting closer and will look forward to any and all suggestions. This may work after all.
