[QUOTE="zako, post: 7841403, member: 629735"] rick1024, how do you bridge a monoblock amplifier for 2ohms? I hope the wired impedance is indeed 2ohms, and not say something like 0.5. Based on description, could it be that the amplifier is bad? How did you set amplifier gains? It may be a good idea to connect DMM and check voltage with a 0dB test tone just to make sure you're not over driving the amplifier. Also, using features like bass boost or bass EQ can have a serious load on the amplifier. Set all bass boosts to 0dB and see how amplifier runs this way. Yes.. Texas heat is a bad, specially in August. My front stage is powered by Mb Quart ref4.80, which already runs hot by itself. Last summer I could see it frequently shut down because of heat.. Then I remembered that I had a +3dB boost a 65Hz on the head unit as an experiment. I turned it off, and problem was solved. [/QUOTE]
