20 Most Recent Pyramid PB681X Car Audio Amplifier Questions & Answers

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.

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.........
