It was "blowed" eh? Recommend contacting a local car audio professional or Pyramid customer support directly here: http://www.pyramidcaraudio.com/ContactUs.aspx

Sounds like the regulator goin. I've read when they go bad it will go full voltage which is 37vdc.
Looks like they use the LM723 regulator. I'm no expert, but may be that simple.
Here's a link to a schematic. Hope it helps

I have a PS14KX. It won't handle any load. If you have any ideas let me know

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage, or a bare wire touching the body of the car

Hi Linda, It's called a pyramid because it starts with one person putting money into a fund, Say it's a guy, He then invite as many people as he can(say 10) to do the same and then those 10 people invite as many as they can(say 10 each x10=100) and so on100x10=1,000) and on(1,000x10=10,000)... see how it grows... And what happens is the 1st guy gets a percentage of the money from the 10 people he invites plus a percentage from the 100 people they invited and it goes on and on, , the people he invited get a percentage of the people they invite plus a percentage from the people they invited and so on and on and it just keeps going and going and the higher on the list you are the more money you get but the lower on the list you are the more you struggle as it gets harder and harder to make money because everybody above you on the list are all getting a percentage from people all down the list until eventually everybody on the bottom of the list looses all their money and that's why it's *******......DO NOT DO IT, If you make any money from this scheme just know it's from people loosing theirs, Take care.........
