I replaced one ground wire that was of smaller gauge than the others. Today I'm going to mount the 12volt converter in the boot with the other gear and ground it to the main star ground. I'm nervous about removing the tweeter protection caps. as they have already saved my tweeters twice from a 3A.M. tuning session miss-adjustment while setting the DSP but I do have a cheap set of tweets that I am going to run in the system with the capacitors removed to check this out.
I'll report results when able.
