We have a say in Hebrew: The beginning of an act shall be thinking ahead.
No, the HD wire is not for us. It is too rigid. A car audio or some other stuff would be better.
Some car audio do not have the gauge they claim. I did a car audio project, needed some 4 AWG kit and ordered one from the US.
The actual cable that arrived was more like an 8 AWG!
I'll repeat my say: After you hold a 0 AWG cable of whatever the length you need, how are going to use it?
No banana plug nor binding post can support it.
Soldering a 0 AWG is not a good idea. By the time it will heat up to melt the tin, the plastic cover will be melted at the ends...
A 0 AWG wire, when used in car battery applications, welding machines etc'. are crimped. So with airborne and military applications.
To press a 0 AWG cable shoe, a heavy duty tool is required. This entire thing can become a project of its own.
Just by getting a 0 AWG wire, you are not yet set.
If you have no choice but to have a longer cable and it needs to be 2x 0 AWG, you need more than that crimping tool. Much more.
There is a reason why most speaker cables are not coming at that gauge and those that does have a hefty price tag.
All I'm asking, once you have the recommanded cable (as calculated) please be kind to share it here. Tell us please what cable it replaced and what were your listening impressions. Thanks.
