Yep, I know about the warranty. I have tried calling them now for the last couple of days and send them a few mails. But haven't managed to get in contact with them.
So if someone knows what a BC2K does at 0.5 ohm I would really appreciate it.
I have seen people think they do 2300-2400W rms, but would like it confirmed.
Edit: I have a dual 1 ohm PSI Stage 3 sub, so I have to go for 0.5/2ohm, and I can't afford a 2000W+ @ 2 ohm amp now.
