Question about Pyramid PB1500 Car Audio Amplifier
I have a PB1500, now owned for about 6 months.. today i noticed the power LED was off on the remote and thus no sound.. i figured it was just a fuse.. No diagnostic lights are on (power/protect) but i know it has power cause the blue LEDs on the side light up.. any suggestions??
P.S. Both my fuses check out as good.. i am lost
Check if the terminals are well connected and also check the sub the pyramid can't handle 2 ohm bridged it must be 4 ohms by the way i but the 2600watts and its not even close that power...

I don't know how you checked the fuses but if you didn't use an ohm meter, you need to confirm that you have B+ and remote at the amplifier.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
If the voltage is sufficient at the remote and B+ terminals, the switching power supply has probably failed in the amplifier.

1. Turn on the device that you want to set.
2. Look for the brand name under the specific device listing provided.
(Note: You will notice that some brands will have more than one 3-digit code. During the
code input process, you may have to try more than one 3-digit code that will match your
device brand and model.)
3. Aim the remote control at the device and press down and hold CODE SEARCH button for
at least 3 seconds until the red LED lights up solid red.
4. Press the device button for the item you wish to program, e.g. TV, DVD, VCR, etc. and the
LED light will blink once and then remain solid red.
5. Using the number keys, enter the 1 st set of 3-digit codes from the list. You will notice
that each number that you press, the LED will blink once. After you have entered the
3rd digit, the red LED will turn off indicating that the code was recognized for the device.
(NOTE: If the code entered was not compatible, the red LED will flash several times.
You will then need to repeat Step 3. You have 30 seconds to enter a code.)
6. After the red LED light has turned off. Press the ON/OFF key. If the device you are trying
to program powers off, then you have found the correct code. If the device does not
power off, then you will need to repeat the process again from Step 3, using another
7. Make a note of the 3-digit code for future use.
