I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.

I have a sony explode1000 watt amp xm 2r1852 hooked up to 2 10" Sony explode 1100 watt speakers, my protection light comes on green and stays on but I don't have no sound .I've checked all the wiring and...


1000W system is enough power to blast your neighborhood. If the + and - connections are correct the speaker balance is connected properly. I assume you have checked the speakers and they have been working fine.
Thus, the problem is internal, within the amp. Make certain that you have selected the proper sound out to the speakers. With the speakers attached, keep switching around from one sound path to the other. Make certain, your source (input to the amp) is proper and the signal is communicating with the amp. If the amp has direct out ports to L/R Center and Surround that you can use wires to connect to the speakers, try that method.

Protection Light Comes on


Sounds like you have an ohm problem, Tryy hooking the positive from one speaker to the negative on the other speaker. Then hook the negative from the first speaker to the negative on your amp and the positive from the second to the positive on the amp this will drop your ohm load and the amp should stop going into protection.

My amp is not working


For the visonik, you should check your speakers. You can use a D-cell battery. Remove the speaker wires from the amp and connect each speaker across the battery (for no longer than a few seconds). The speaker should pop each time the wires are touched to the battery. If they don't, the speaker is defective (assuming the battery isn't dead).

If the speakers are OK, you need to confirm that you have a good signal feeding the amp. You can use the RCA cables from another working amp in the vehicle. Do this with the amp that had the power light lit.

If you have signal going to the amp and the speakers are OK, the only two things left are the power supply feeding the amp (from the battery) and the amp. If you have B+ and remote voltage AND a good ground, the amp is defective.







For the pyramid, the amplifier probably has shorted output transistors. The amplifier will have to be repaired.

Sony XM-2200GTX...Power, Green Light, All OK, No Sound!


Sony generally drives their power light from a source that does not rely on the amplifier's switching power supply. This means that it's not a good indicator as to the health of the amplifier.

 

As long as you have B+ and remote voltage, it will light up. Since you've tested the speaker and the signal source, I think the amplifier is likely defective.
