Anybody here tried this,i read on some forums that it works well without going into thermal protection but still want to be certain before i try it.

Why you wanna try this?

how much power you want to get out of the amp at this 1/2 ohm load?
max?

If you have a poor electrical system, you run a high rise of damaging the amplifier.. Lots of guys do it, but running such low impedances places alot of stress on the internal components.

oh well nah i was just curious like if i wanted to burp for spl purposes

that's slightly different.. most amplifiers can handle the short burps used for SPL and running at the lower impedance can give you a decent advantage, especially when battling with impedance rise.

of course, the same precautions will apply.. i.e. ensure your voltage does not drop too low because you will still risk damage..

I ran a pair of Sundown amplifiers at 0.5ohm for many SPL competitions with no issues.. Have seen lots of other brands handle the 0.5ohm for SPL use with no problems as well..
