As far as amperage rating yes. Welding cable is not as flexible though.

Do you think I should make the switch from cca if I'm running around 2500rms..... Think I'm going to get rid of my Hifonics and grab the Orion xtr extreme 2500.1d

You do not "have" to swap to ofc but it never hurts. But 1/0 welding cable is not equal to 1/0 car Audio. 2/0 is what your after for welding cable. Also your wire is based on amps. Most cca is good for 250a for 1/0 and ofc is rated for 300a for 1/0. If your running 2500 real watts at 13v that's 192 amps or so. So in theory the cca should be fine. The biggest cca issue is that it will corrode faster.

Welding cable is true AWG rating size. Car audio 1/0 is oversized. If my garage wasn't destroyed and I could get to my wiring I would take a picture of 2/0 and 1/0 welding cable with 1/0 Sky high and 1/0 Knukonceptz wire.

Most CCA is good for 250 amps in a 20 foot run. If you need more I would recommend going with OFC.

Checked voltage drop from battery to amp and only lost .1 so I'll stick with what I got.

was with voltage drop with system playing... hopefully so

It wasn't because I know I have voltage drop with system playing, but I have ordered a bigger alt (still on stock) and adding a 2nd battery soon to help with that.

I have side by side pics of welding cable and Knu power wire both 1/0 and see no difference. Just the strand count is less in the welding cable, thicker strands, than the Knu.
