Dear Cliffey18

I think you have to change protection diodes,Sometimes they seem to be ok when not load but when the power gets in they change the behavier or it can be the regulator ic which is fualty.........

I hope your problem is gonna be solved
thank you

We installed the amp with more than enough gauge wire, and a fuse. and after resetting the ground strap we got the amp to start working after about 3 minutes at medium power we was adjusting the sound via...


Hi,
In car audio always make sure that you are feeding your amplifier with the voltage that it requires, usually 12v to 14v (some amplifiers can do 12v to 18v). If you have a voltmeter, check your voltage reading if its reading 12v above, if it reads 11.9v below & just stays there & keeps on going down then your problem is with your voltage.
The possible causes of the protect light to turn on in a amplifier is: 1. low voltage - the amplifier is not running on its required voltage / is not getting enough voltage 2. thermal protect - too much heat, usually this occurs when an amplifier is in a tight space & the voltage keeps going down this will cause heat. 3. shortage - wire's are touching each other 4. poor ground - always make sure you ground your amplifier to your vehicles chasis
Hope this helps your concern. Have a blessed weekend.

Green and red light are on my pyramid amp and its not working


It could be even simpler than that, yes an improper impedance rating on an amp will cause it to overheat, but should function temporarily until it reaches peak temp. If the outputs were blown the protect light should not light up being that they would need to work to cause the protect light to come on. I would double check all of your connections, one small little crossed wire would cause an amp to immediately go into a protect mode.

My jcpower car amplifier is not sound come out


you are probably getting a high voltage jump when you turn it up which will throw the amp into protect mode the only thing I can think of is trying a voltage regulator for your stereo

Pyramid PB449X In Protect Mode


The protect light is a notification that the amplifier has reached a set temperature and shuts the amp down till it cools off. Look for the thermosister on the heatsink and follow the circuitry back to the control chip. Once you get that fixed the amp should power up until it gets too hot and the protect circuit kicks in. I had one of these amps for a while and the circuit was very touchy. Regards, rcampsr

My amp turns on and off


Sounds like there could be a short somewhere. Check to make sure that there aren't any (exposed/bare) wires touching each other or if there is a bare spot of wire touching something metal. Check both ends of all the wires. A speaker wire may have come lose and is shorting out against the frame or some other place. Usually if it goes straight into protection mode or you're popping fuses you have a short somewhere. I assume the capacitor you installed is somewhere on the power line, which would be for helping with
noise. You can also try disconnecting your amp from your stereo and see what happens but leave the speakers connected, you don't want to run the amp with out a load on it (the speakers). If your amp doesn't go into protection mode when the stereo is disconnected, then you have a problem with the stereo and not the amp, assuming you already checked for any possible shorts first.

PB1500 no diag. lights - Power - OK


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.

Rockford Fosgate Power T20001bd goes into protect upon power up.


In most of Rockford's amps, the low voltage detection is connected to the remote input. If the remote voltage is too low and they use the same circuit on this amp, it could trigger the protection circuit.

 

Disconnect the head unit's remote from the amp. Use a fuse holder with a 3 amp fuse to jump between the B+ connection and the remote terminal of the amp. If the amp powers up, the head unit's remote output may be defective. If it blows the fuse, the remote input or part of the power supply is damaged. Do not try it with an unfused jumper.

Protection light and nothing. ??


How about the speaker itself? This problem can be caused by a blown or defective speaker. If you disconnect the speaker wires from the amp, do you still get the protect light?
