You need to investigate your voltage source (PSU). This isn't paranoia. This flat out won't happen on two different machines, built to drive identical speakers. No coincidence.

Quoted from Edster:

resistance of the speakers... I never thought of that. I will try today. Thanks.

Yeah, if the coil melted, which sounds like what happened, all kind of neat things can happen that can screw up an amplifier. I've had a lot of fun repairing guitar amps of all types due to this. Essentially, the speaker starts to need more power, which draws too hard on the amp and kills it. Very common in lower wattage amp set ups, especially solid state.

Quoted from Edster:

Interesting. You are probably right as I cannot figure out what else could cause this. I have a the pro audio speaker upgrade. There is a coil that came with it, I guess that is the enemy right now. I think I might just install the old speaker.

That's a good piece of info that the speaker is not stock. What do you mean by the coil that came with it and what is the wattage/ohm rating of this replacement speaker?
