Mr.
glupsonIt’s obvious that you have nothing smart to say, so you use derogatory language.
#0 or #00 or #000, yes. Most cables out there are #12 - #14 awg and are insufficient for higher DF SS Amps.
Yes, they are cheap to make and easier than doing a #0 awg cable.
I just made one this Sat. It is difficult to work with such a cable (#0 awg). I had to fight with it a half day to get it done.
Also materials are more expensive. They waight 1.85 kg. each (x4).
Design issues. A MIL STD or airborne unit MUST go through some maticolouse design phases. It shall assure a perfect product.
The way today speaker cables are made, is the worst. Nothing is professional. A big shame for all involved.
