I never had an amp overheat on me so I do not know what exactly happens. From what I understand, the amp basically shuts down. Why does it shut down; due to a thermometer or a blown fuse.. etc.? Also if one were to push an amp down to say .5 ohms, this would be done with a mono amp, right?

Thanks

Usually amps go into protect mode because of of unstable impedances (not all amps can go to .5 ohms) or because of thermal overload. If the amp is hot to the touch, chances are it's being pushed beyond it's limits and harming the speaker it's attached to.

How would someone know if an amp can go beyond 1 ohm? As far as I have seen farther than an ohm isn't advertised. If a hypothetical amp that was set to .5 ohms and was supercooled would it play longer than a few minutes?

In theory, yes. In all practicallity, no. Most run of the mill amps arn't made to handle that impedance. Only a select few competition amps can. Either find a way to wire your subs to >2 ohms or get a competition amp.

I think there was a thread started on this subject not long ago, try using the search and seacrh for .5 ohms.
