Sony Xplod XM-554ZR Car Audio Amplifier going in to power protect mode

Problem with Sony Xplod XM-554ZR Car Audio Amplifier

Wont stop going in to power protect mode

I have a sony XM554ZR amplifier installed in my car. I have checked and double checked the wiring but still it will only go in to power protect mode. Any advice / suggestions are welcome.

I have an amp installed but can not get it to come out of power protect mode. All wiring and fuses have been checked. I have disconnected all RCA and speaker wires and put a multimeter accross the ground / power (14.4 result) and accross the ground / rem (14.25 result) Does this mean that the amp is blown or is there any thing else that I should try?

does it still do it with speaker disconnected?

iuf not then speakers are issue.otherwise amplifier needs to be replaced.

Crack the windows and drop the sony system and get your self a nice mono block class d amp 1000 rms should be loud enough btw bild your stereo based on rms power not max power rms is the true power you got so like 2 500 watt rms 12s on a 1000 watt rms amp or just a 1000 watt woofer it will be jsut as loud as the 2 12s

Its in the amp and sub itself, what kind are you running, facing the sub forward helps amplify the sound forward and vice verse  id seal the boot up with sound deadener or poly-fill  the less movement in the car the higher the chance the bass can travel, if its the thump you want make sure you have the lpf (low pass filter) switched on the amp, raise the gain and if you can do it on your amp bridge the wires, more info would be great on what your running. if you have the slat feature on head unit turn that up, bass frequency on head unit and amp should be between 55 to 80 up to 110 on both amp and sub.

1985 Honda civic radio speaker sound is low

Problem with Sony Xplod XM-554ZR Car Audio Amplifier


I have a 1985 Honda Civic which I installed a Sony CDX-GT260 Car Stereo 50Wx4. I hooked up 2 Kenwood speakers sitting in oval boxes on the parcel tray above back seat in addition to the 2 in front doors. Sound is OK but I wish it was a but "fuller" with a richer base. Someone said fit an amplifier under the seat. Will this help and / or other guidance please.




First of all please check if the speakers are connected in phase. That is if all the positive and negative terminals are connected OK. Simple way to check is to turn the fader control first to the rear and then while playing some music with heavy beat ( dance music ) turn the balance to one side. Listen and see if you are getting good bass. Then turn the balance and bring it to the middle ( 0 ), when you do that if the bass is becoming flat-- one of your back speakers are out of phase and canceling bass. If thery are in phase the bass should become full and rich. Do the same by turning the fader to the front and try swinging the balance. If all is Ok , yes you will need an Amplifier to satisfy you. Make sure you buy something that can match the power of the speakers you have installed in the car.

The out of phase syndrome is a very common problem.
