    It's possible that you have speakers or subs running at too low of an ohm load for your amp to handle. Tell me what gear you have hooked up to it.

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.

Fuze blowing

try: a shorter ground cable, a bigger ground cable or sanding the surface where you make your ground. a lot of amps will tell you the ground should be no more than 3 ft and for any the shorter the better

Pb1281x pyramid crystal 2ch mosfet amplifier 1600w what size fuze i got a 20amp in it it blows when i got it terned up

Hello sunshanel,

You did not say what you have the amp connected to and what the impedance load is. It is only stable at 4 ohms and if a lower impedance is connected, say 2 subs in parallel, it would try to produce more power when you turn it up and would most likely blow the fuse. 20 amp sounds right for the amp. The power rating of 800 watts per channel is peak power, not RMS, and many low-end manufacturers tend to state bigger numbers in the ratings.

Hope this helps.

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
