You didn't say how long it ran before it quite and I assume the red light you are refering to is the protection circuit engaged light and not the power on light. But from the info you did provide, I'd say that it sounds like you may have blown some of the main output transistors/MOSFET's. If so, it's time for a trip to the repair shop. Sorry, for the bad news. If just turning your car on caused the outputs to fry, then I wouldn't be surprised to find that you have either bridged the speakers wrong or by some means you have put the wrong speaker load on the outputs. Ask someone who knows what they are doing, if you have your speaker loading correct. This person might not be a car stereo installer as sometimes they don't know how to load an amp correctly, especilly when it comes to bridging. Good luck.

Bought a car and this amp was in it(Pyramid Crystal PB781X 2ch MOSFET). it is missing the fuse. what fuse does it require?

25 to 30 amp fuses are the most commonly used fuses in any amp and since yours is a 1000w amp, I would use the 30a.

Green and red light are on my pyramid amp and its not working

It could be even simpler than that, yes an improper impedance rating on an amp will cause it to overheat, but should function temporarily until it reaches peak temp. If the outputs were blown the protect light should not light up being that they would need to work to cause the protect light to come on. I would double check all of your connections, one small little crossed wire would cause an amp to immediately go into a protect mode.

Pyramid PB449X In Protect Mode

The protect light is a notification that the amplifier has reached a set temperature and shuts the amp down till it cools off. Look for the thermosister on the heatsink and follow the circuitry back to the control chip. Once you get that fixed the amp should power up until it gets too hot and the protect circuit kicks in. I had one of these amps for a while and the circuit was very touchy. Regards, rcampsr
