If there is no protection light on, be sure the input is on. Some head units need to be turned on manually (factory set to OFF).
Verify the subwoofers are wired properly.
A list of your components would help to solve your problem.
If it is new, it should still be under warranty - worst case scenario output transistor(s) blown, or power supply bad.

If there's no sound at all from the subs and you know they are good, there's probably no output from the amp. It's either wired incorrectly or it is defective.
If there's some sound but just not loud enough, then either the amp is not getting enough of an input signal from your head unit, or the amp settings are not adjusted properly. Adjust the crossover and gains for the best output to subs. LP filter on, crossover frequency at about 80-100Hz, and gain to maximum without distortion when head unit volume is at about 3/4 maximum.
Hope this helps.

SOURCE: how do i drop it down to 0.5 ohm
there are no settings on the amp, if it is made to be stable at .5 ohm you will need 8 voice coils to make .5 ohm, if your subs ar 2 ohm, you will need 4 coils to make .5 ohm when hooked in parallel

Disconnect the speakers and then try it again...there may be a shorted speaker or wire if the amp comes out of protect after you disconnect the wires...if the amp stays in protect after you disconnect the wires then there is a problem inside the amp with the circuitry and it will need to get serviced by an electronic tech
