is it ever safe to run an amp @ .5ohm?

just like the title says, is it ever "safe" to run any car amplifier @ .5ohm or below 1-ohm mode? what are the exceptions?

i currently have 2 dual 4-ohm subs and a sweet deal might come thru for another pair of dual 4-ohm subs. my only amp is an hifonics brutus BX1000D which is 1ohm stable. so im seeking advice whether not to risk my equipment and whatnot.

can anyone point me in the right direction on how i would go about this?

there are some amps that will run .5 ohm, if u run that brutus at .5 ohm it's goin to blow and your subs will most likey be screwed up to

If you don't have money to waste then it's probably not smart.

A lot of reputable amps will run at that load. Keep in mind you are going to need the electrical system to support it tho (HO Alternator, Deep cycle battery, Big3, etc...). Also you'll have impedance rise...so it should help some...

I'd try to pick up a modded MTX 1501d if you can.

It all depends on the amplifier, and if you have the equipment to keep up with those high current draws.
