SOURCE: Re: Pyramid PS-36kx power supply buzzer sounded,red light came on

Hi! I saw your question, and maybe this will help. I also have a Texas Star 100w amp, and this same power supply. Even though the nominal draw for your equipment is way below the rated amp flow of the power supply, when you key up, and the output on the amp is at max, you are drawing the limit of your power supply! Try running this setup at a lower linear output. You don't need the full 100 watts to get out! 60-80 watts is aplenty! You should start at a low output, and slowly increase the output(while keyed up), untill the power supply starts to complain.(buzzer/light). This is what your limit will be. The only other cure, is a MUCH bigger power supply. Unfortunately, I cannot afford a 60-90 amp supply, so this is what I am forced to do to use the one we have. Also,keep your cb's output very low when using the linear amp. These amps are supposed to get a low signal from your radio, or the linear amp is overdriven. (noisy and unstable. Hope this helps you! 73's to you! jimsjinx

Why does the red light come on when i hook the power wire up to my car amp?


Could be fried, or connections are wrong and its not getting a good ground. If you're not getting power most likely its fried. Check fuses etc. Take it to a brandsmart and have them test it

This is hard to explain and what needs to be done is wire in parallel both subwoofers. This website will help just put in the amount of speakers and amount of ohms each and it gives you diagram.

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.

Amp over heating and cutting off


sounds like the Impedance of the speakers does not match that of the amp, therefore the output stage of the amp is trying to compensate, driving the amps too hard and eventually causing the thermal cut out to activate. Check the ratings on everything are compatible before you start sending it off to be fixed.
