Hey guys. Been fiddling around with my new osub and I've got a couple of questions I hope I can get answers to.

1- What wire is clapton usually made of? Because the helmet CLP coils come with a "Fused Clapton Dual Core" I think I get the core part, but what is the wire used?

2- Anyone have an idea of what is the best mode to use this at? I'm right now on temp mode at 550F, 20W and 0.38 ohm resistance, SS TCR 00092

Any help is amazing. Thanks in advance :-)
