Hi guys, I'll repeat my question: Is it possible to run H900 at 2 ohms using 4 pair of MJW21195/MJW21196 with 120-60-0-60-120?
What power expect?
Also, here is schematic for the guys who like challenge. That is something more then 1KW SMPS from diysmps forum, but I reformed that in two step, for H900 amp.
Cheers.
