Question about Sony XM-752EQX Car Audio Amplifier

1 Answer

No Sound/ lights flashing on Amp

I have a Sony XM-752EQX amp that has all of a sudden quit working. I get no sound from the speakers. The unit powers up with the power light coming on. In addition to that the over current, offset, and thermal lights all light up green and flash continually in some sort of a coded pattern. I can't find anything to tell me what the flashing indicates. They all three flash in the same pattern together. Any suggestions as to what is wrong?

Disconnect your subs from the amp. If the lights go out then your sub is blown and is putting the amp into protect. If the lights keep flashing even with the subs disconnected than the Amp is toast.

Premium Bose XM/AM/FM/CD/Radio in 2004 GMC Envoy XUV has no sound. First the AM/FM quit working like the unit did not see an antenna. I had the body control module re-flashed which fixed my speedometer,...

You should be seeing BCM trouble codes (DTCs) for the radio with a code reader. I am assuming you are hearing something (noise) from the speakers with the radio on. If so, you may have lost the programming in the radio - you could try re-flashing it. However, that radio has a number of memory locations that are set whenever the radio is turned on - one or more memory modules in the radio may now be faulty.

I have a Xplod XM-554ZR Car Amp and the green light is blinking it worked just befor and now i have no sound

The amp is in protection. Disconnect any speaker from it, then turn it back on, if it's not flashing, check your speakers with a meter and check speaker wires for shorts. If it's still flashing, you've blown the protection circuit and it needs to be replaced or repaired. Hope this helps

XM-552HX ofside led turn yellow

You may have an issue with the impedence of the woofers causing the unit to go into protection mode. Make sure that the woofers are no lower than 2 ohms at the amp. This can be done with a voltmeter to check. You are better off running the woofers at 4 ohms if possible. If you disconnect the speaker wire from the amp, does the yellow light still come on? If so, then there may be a problem with the amp.

Amp went into protect, but front speakers sound distorted too

If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.

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.
