Your WAY WAY underpowering your TDXsI don't know about the other ones you listed but i've had a diamond d5 1200.1 running two tdx subs for the past 3 years and its a very good efficient (sp) amp. I spoke to an engineer at diamond and he said that the 1200 usually puts out about 1500 watts. He told me that it is not a fully regulated power supply but a semi-regulated one. They put out full power at 11.5 volts.
FYI...........
Diamond best engineers left years ago now they have turned into
a company of chinese importers -
