LOL, Yah going from 2 ohms to .5ohms is nuts on that amp. I think off our talks your impedance rise is probably high enough for it to take it. Do another power test when you have time.I have this thing at .5 ohms right now and its a beast. It dosent even warm up even at such a low load. Dont get me wrong im sure if I beat on it hard for a half hour it would start to heat up but so far its doing great...I have 3 stinger spv70 batteries and at full power im dropping down into the mid 11v range before I let off. It is true though what they say... If you keep adding batteries this amp will just keep getting stronger...
