Exclamation PCX1250 2ohm mode Problem

Hello all,

I have been having troupbe with my amp. The PCX1250 works fine with either 4 ohm sub but when connected together for a 2 ohm load on the amp the sound level is low and distorted. since both subs work fine connected on their own I have to assume that there is a problem with the amp. Has any one else ever had such an issue? I do failure analysis on power supplies for a living so I'm sure fixing the amp would not be a problem just hoping someone might have some insight into what the root cause is for this failure mode.

Check the 0.1 ohm 5 watt emitter/source resistors to see if any have broken leads.
