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.
