    My Sony Xplod XM-554ZR worked till my factory radio went out. After replacing the radio, rehooked amp to new Sony unit. Now I have power to amp but no sound from subs.

Xplod XM-554ZR Car Audio Amplifier: powr/protect light comes on red not green...


Hi, disconnect all speakers from unit and try again - if red light still shows then your amp has died.
If the light goes green, then start testing for shorted speaker/wiring. This includes speaker wiring to vehicle shorts - there should be an o/c reading on your meter

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

Power Protection Light Will Not Switch Back to Green


Disconnect all speakers, then turn the amp on. If there is no internal problem with the amp, it will go green. If it does go green, reconnect your speakers one at a time with the amp off then turn it on. when you connect the speaker that's causing the problem, the amp will go into protection. At this point, it's one of two things, a bad speaker wire (screw thru it or touching another terminal) or a bad speaker(burnt voice coil) to test that wire, disconnect the wire at the speaker and turn on the amp, if it's still green, all's well in the wire department. Meter the speaker with a multimeter on resistance, if it's blown the meter will read 1.... If you don't have a meter, connect the speaker that's having the problem to the other channel and test again, if it goes into protection, you've got your answer. Bad speaker. Hope this helps

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 sony xplod 1000w xm-1652z doesnt work anymore


First off, according to the manual, the protect light should be green. That's normal operation. If it is red, that's a problem.

If it does go red, disconnect all of the wiring to the amp except the +12V and ground. Short the remote connection to the +12V to force the amp on. If the protect light still lights red, the issue is inside the amp and will need repair. If the issue goes away, try reconnecting one wire at a time until the protect light goes red again.

Red light


something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.
