Question about Sony XM-2150GSX Car Audio Amplifier

1 Answer

Amplifier keeps running overcurrent

Whenever I run my system, it hits for a few minutes, then the overcurrent light comes on, shutting off the power to the amps. It worked fine for over a year, then it just started doing this. What can be done about this problem???

Sounds to me like you are overheating the amp, try down tuning the peak level of the amp, and also if there is anything around the amp clear it away, check if the fan is turning on, you may need to replace it,

My SB300 keeps shutting off after 15 minutes, what is the problem and how can I fix this?


Is anything running hot in the system? could cause the system to shut down. Does the main amplifier get enough cooling?
Just a few questions I ask myself. Always difficult to answer questions about electronic things, if you are not behind the system yourself.

Overcurrent lights comes on whenever my amp is on


this can only mean 2 things, either your over working the amp, which means your amp is trying to push power that it don't have, and it's getting hot which is known as thermal mode. and the other reason can be that make sure amp rms. matches the rms. of your subs.

Its on over current


when the overcurrent light lights up, this means the amp is being run too hard or too loud. try cutting the gain back a little. i always hated putting in the sony amps that had those lights on it. it seems that when you turn it up and get it sounding good the light comes on.... if the overcurrent light is on all the time and it doesnt make sund....the amp could be bad. good luck.

I have a Jet Audio 600W car Amplifier and everything is wired up proper etc. But the power keeps coming and going off every few minutes and the flow of power is not constant.


hows the amp wired from the load of your subs? 2 ohm 4 ohm ect. if the load is too low the amp will shut down and cool off then com eback on, thermal overload protection. if your amps bridged at a 2 ohm load, it more than likely cant handle it so run it stereo mode,

I have an HP Pavillion dv9500 laptop. After shutting down, all the keyboard lights to the right of the power button stay lit. This shows the power is not shut off but should be. Any solutions?


First of all, is the laptop on charge? Usually when the laptop is on charge there is a light somewhere that remains on until it is charged. After charging, the light goes of and if the laptop is not used for a long time, the battery usually discharges a little and the system senses this and recharges it as top-up and the light comes on, then goes off once charged. If your laptop is not on charge, then there is 2 things that could be the cause. 1) It is not shut down properly (on stand-by). 2) It may be downloading updates and it would probably shut down later, depending on the size of the update, it may take a few minutes or up to 1 hour. If in 1 hour the light is still on, then there is a problem with the laptop and need to be checked by a professional, or, altermnatively, turn it off a second time and see if the light still remains on. Lastly, you did not state what kind of lights remain on, Power, Charging, Standby, etc. it is difficult to help you with your query as the problem could be the laptop itself. There are other things that could keep the laptop on, and that may be if your laptop is connected to a network. Regards.

It doesn't matter what you do, that the system will power down after being on for exactly a minute? Or do you find that when you try using it a few times in a row that the shut off happens a little sooner each time? Did this suddenly start happening or was it something that began occurring gradually (meaning it would power on for an hour and then auto shutoff)?

It sounds to me like some electrical component inside is failing and that the self-protection circuitry design is kicking in. Or it could be that the power transformer is worn out and can't maintain power for more than a minute.

Keep in mind that repairs to these older electronics can end up costing as much as it would be to buy a new unit (and new units offer much more technology anyway).

Does it shut off for a couple of minutes or a couple of seconds? Is the amp hot when it shuts off? Are you sure you have the speakers wired to an acceptable ohm load for the amp? Have you measured the voltage at the amp (across the B+ and ground terminals) to make sure it's not dropping too low on hard bass notes?

Same problem here...I determined that if you unplug the receiver for a few hours, it will work again for a week or so.  Someone else on this website said that it had something to do with the power relay switch:

Amp overcurrent problem


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 (overcurrent), the amp likely has blown output transistors.
