The problem that I have with your Combox chassis ground is that you will be sharing that chassis ground with a high powered amplifier. Although the assumption is that the Combox chassis is fully isolated electrically, nevertheless the assumption is that it is fully isolated electrically as is in that chassis location. Not to share that location chassis ground with a high power amplifier.

Perhaps is no big deal, but again there are better ground points than this one.
Hmm never thought of that Technic. I don't want to take any chances. Where is the ground point you mention? Near the battery? Thanks for the feedback.
