Just curious, which single wire, solid core, 9 awg cable/wire do you use for speaker cables?
On the power side of things, you basically described Romex, which some well-regarded folks actually believe would make a good power cord..
I`ve spendt years developing a 4-way speaker system and it has never been singlewired but if I had to use just one set of wires I would still use our norwegian Nexan-made pfsp standard romex-equivalent.
9awg is not enough though to feed a grown woofer, give it 7awg* and your amp will show it`s full potential, assuming it`s feed through solid core pc`s, no filters.
Back in those days I came to discover quite a few things, like how to make 100% inaudible/lossless IC`s, speakercables, spdif coax & powercords. Took me some years and endless testing to comprehend what I`ve stumbeled over. Sometimes the truth is so simple it`s taken for a joke..
