Not all amps share a ground from the chassis to the RCA inputs or the speaker outputs, where as some amps the ground wire input is connected to the rca input to the speaker output there is no break in the signal. The old instructions when the first DD-1s came out you where told to use the negative power wire for the negative probe, then some where it got switched, but still some amps with tiffany style rca inputs that dont work on and you need to use the amps ground for the probe and not the negative output. Ive ran across this issue so many times, and Ive been using all my smd tools for years. I actually have the 4th DD-1 and CC-1 made before they where released publicly

Well, the Saturday thing is normal, but I emailed on a Thursday, Wednesday, Monday. I only emailed recently on the 2nd of May, which is a Saturday. I do understand the Saturday email thing though. I connected my DD-1 and CC-1 lead's to both my amp and my friends amp. All though the speaker terminals, I tried both right output and left output of each terminal. I didn't think about using the negative power wire for my connection, I'll have to try this next time I am over at my friends house. As for the amps tested, I used a Skar Audio 1500.1Dv1, JL Audio JX 360/4 these amps being mine, and my friends amps, which were an Apline 500mrp and a Kenwood Excelon Gouriki Series 4 chan amp. I used the same way to tune all amps. Leads to positive speaker and negative speaker in their respective places. The crossover for the 4 channels were set to off as well as on my headunit. For the DD-1/CC-1 I saw that I can send them in to get calibrated, I think I will go with that option. I don't think I did anything wrong when using the DD-1/CC-1 but I am human and am not perfect.
