I'm having problem with a Crossfire vr804 amp. I'm using a 30-amp power supply in my house to run the amp and I noticed that the protection light comes on for 1-2 seconds but after 1-2 seconds it works just fine. Should I be worried?

I will have to say you are not giving that amp enough current. Those are monster 4 channels that pull 80a at modest volume. If your only running a 30a MAX powersupply you are tapping it out and are going to blow your amplifier and PS if you keep it up. Do you have some sort of 12v motorcycle battery as a charge source?

Turn the gain alway down and see what happens.
