Question about Sony XM-2002GTR Car Audio Amplifier

Protection light keeps coming on

I actually have an XM-2002GTW, but couldn't find that in the listings. Anyway... I have it hooked to a Pioneer Premier 12". I hooked it up Saturday and it worked all day Saturday and Sunday. Sunday evening it stopped working. I hooked it to a friends sub and it played fine. He hooked his stereo to my sub and it played fine. When we put his amp in my truck, the fuses in the amp blew. I'm guessing the fuses in my amp are trying to blow but the protection circuit is saving them. Also, when my amp was working, my battery meter was dropping and my lights were dimming. I assumed this meant I was not getting enough power to the amp, but if I'm not getting enough power then why am I tripping the protection circuit and blowing fuses in my friend's amp? Any help would be appreciated.

Check the wiring between the sub and the amplifier. That's seems to be the only thing left that could cause a problem. If it's shorted to ground or pinched so the conductors are shorted together, it could cause the symptoms you listed.

I researched your amp and it looks like its not even 2 ohm stable :( the problem with these companies is they lable there amps 1200 watts MAX, that means they tested the amp in a perfect enviroment and the amp fried somewhere in the ball park of 1200 watts, your best bet is to save your money and buy a nicer amp that is two or one ohm stable... that being said the best way to wire your subs is in series

I have a sony xm-2002gtw amp and i want to bridge this amp to get the full 1200-watts,how would i wire my speakers i have two 2-ohm dual solo baric

In order to get full power from the amp you need to wire you amp ( high level input of the amp ) to your cars rear speakers both left and right ( negative to negative positive to positive ), once done you can wire your speaker to the left and right speaker output of the amp. Comment if you need more assistance. Best of luck

Xm-2002gtr amp keeps kicking protect light on

check your amp and speakers and make sure their both hooked up 4 ohm instead of 2 ohm because if you have 1 set of voice coils on your speakers they can only be hooked up four ohm and not bridged to your amp because if you keep trying this you will lock up your speakers if the speakers are only 4 ohm than just hook them up regular to each channel on your amp if your trying to brigde four ohm speakers to your amp it will keep going into protect or worst case scenario you will fry your speakers and you can check your ohm with a ohmmeter trust me my brother owns a stereo shop

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.

Hi i have a 600 watt sony xplod amp model xm-554zr and it recently stopped working. when i turn my car on the amp turns on but only for a sec then the protection light comes on, on the amp and it wont...

sounds like maybe a speaker short, try unhooking your speakers and then powering up your amp, if it then powers up with the speakers unhooked try hooking up each speaker one by one untill the amp goes back into protection and then you have your bad speaker.

My amp protection light keeps coming on

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

Protection light

You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
