I have a Sony X-Plod amp 760w 2/1 channel xm-1902gx. Everything is connected properly and the amp contains 4 lights (power,over current and two others). Power lights up like it's supposed but the over current lights up as well. I am unable to get any sound from it. Can you help me before I trash the amp.

What does the offset light mean on sony xplod amp


THIS IS "DC OFFSET". MOST AMPLIFIER PROTECTION CIRCUITS REACT TO THIS CONDITION BY SHUTTING THE AMPLIFIER DOWN. THIS IS A CONDITION, NORMALLY BROUGHT ON BY SHORTED OUTPUT TRANSISTORS, THAT ARE TRYING TO PASS THE POWER SUPPLY DC CURRENT TO THE SPEAKERS, WHICH IN A MATTER OF SECONDS, WOULD BURN THE VOICE-COILS IN THE SPEAKERS. MOST TIMES THIS WOULD BE CHARACTERIZED AS HOOKING THE SPEAKERS UP AND OBSERVING THEM SIMPLY POKING OUT OR IN CONSTANTLY WHICH CREATES MUCH EXCESS HEAT. THIS IS WHY THE AMPLIFIER WILL SHUT DOWN TO PROTECT THE SPEAKERS. YOU CAN TRY TO DISCONNECT THE SPEAKERS AND THE RCA INPUTS THEN POWER THE AMPLIFIER UP. IF THE DC OFFSET LIGHT STILL ILLUMINATES, THEN YOU WILL HAVE TO HAVE THIS UNIT REPAIRED. ONCE REPAIRED, BEFORE REINSTALLING IT, MAKE SURE TO CHECK YOUR SPEAKERS FOR DAMAGED VOICE-COILS, WHICH COULD HAVE BEEN THE PRIMARY CAUSE OF FAILURE. OK. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE....V

Sony xplod amp(XM-1652Z ) power/protect light


if your amp is overheating your sub is needing to much power that the amp doesnt have.
if its cutting out and the red light comes on you need to check the wiring. nothing not even the tinyest speaker wires can be touching.
proper wiring would be your best bet.
but i would upgrade amps.
cheap bang isnt reliable.

When the amplifier shows an offset fault, it's generally because there is DC voltage present on the speaker terminals. The amp has shut down to protect the speakers.

Sony explod 800W amp


If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) 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 remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

Sony explode amp for my car


Try disconnecting everything but the power connections. If the protection light still comes on, then there's a problem in the amp. If it goes out, then there's a problem elsewhere. In that case, hook up one speaker cable at a time and power on. If the protection light comes on, then either that speaker is bad, or you've got too many speakers connected to that one amp output. Too many speakers connected together can cause an overload and trigger the protection circuitry, or worse, blow out something out.

Hope this helps, and please rate my advice.
Thank you, and good luck!!

Are they all green? If so, that's normal. They go red (or maybe amber?) when the protection circuit detects a problem.

No Sound/ lights flashing on Amp


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.
