Question about Sony XM-SD22X Car Audio Amplifier

Amplifier won't turn on

I have a SONY XM-SD22X, and it was working fine. The LED light turned off and it did not want to turn on again. I checked the fuses, and they were fine. I read the manual and it said to check the ground. I checked it and it was working fine, but know it doesn't want to turn on again. I already checked the fuses and they are fine. So what is the problem?

Check your power cable as well, and also try to relocate your ground wire to a another place in your car...

The red light turns on? how do i make it go off?

The red light is usualy an indicator that the amplifier is going into protection. There could be a number of reasons that this might happen. Here are some: 1. the load that the amplifier is trying to drive is not compatible with the amplifiers specifications. 2. the cables leading from the amp to the speakers/sub woofers are shorting somewhere. 3. the amplifier is heating up above its capability. 4. the amplifier is not recieving the apropriate amount of power. Check if any of these are the reason but if you give me more details such as when does the red light go on and what you have connected to it and how, i will be able to better assist you.

XM-552HX ofside led turn yellow

You may have an issue with the impedence of the woofers causing the unit to go into protection mode. Make sure that the woofers are no lower than 2 ohms at the amp. This can be done with a voltmeter to check. You are better off running the woofers at 4 ohms if possible. If you disconnect the speaker wire from the amp, does the yellow light still come on? If so, then there may be a problem with the amp.

Amp LED light turns on then off

You need to use a multimeter to confirm that you have both B+ and remote voltage at the amp.

I need a solution for my amp

Your XM-SD22X amplifier only has 2 channels. If you want to run 4 speakers then you could parallel 2 speakers on each channel but you need to check that the impedance is not too low. If it is too low then put 2 speakers in series on each channel but this will not be as loud. Regards
