You simply have a speaker shorting in your car. Either an old speaker with a bad voice coil (short) or a speaker who's contact(s) are touching metal. This type of short or grounding will cause the internal audio amplifier to shut off to protect the radio's output circuit. To diagnose which speaker is the culprit, you'll need to disconnect all speaker leads from the radio and one by one re-connect them until the output shuts down again. The safe way to check is with a voltmeter. If you connect one side of your voltmeter to ground and test each speaker wire lead for continuity, you'll hear an audible "beep" whe you find the grounded wire/contact. A professional car audio shop can diagnose this for you if you're still having difficulty. Hope this information was helpful.

I have a 9-3 Aero convertible. Yesterday when I turn my radio on it went to XM preview. I can't get it to switch to AM or FM. What can I do?


unhook the negative battery cable for about 5 minutes, then rehook it, all things should reset back to factory settings after that.

2008 Nissan Altima radio (AM/FM/CD) does not respond to buttons except on/off volume. It was playing an FM station (cant't tune/scan) and now plays a CD that won't eject.


2008 Altima radio-the sound just quit working. Everything else seems to be OK. I can change the radio stations, but no sound. Is there a fuse that could be bad?

When i turn up the volume the deck turns off then turns back on


What kind of car do you have the stereo in? It sound exactly like a bad ground wire. To trouble shoot this, simply find a good clean ground point to hook the black wire from the radio to. you can usualy find somewhere behind the dash that the factory has grounded things to. I asked what kind of car, because some fords, and nissans do not have a ground wire in the factory radio harness, even though the adtor harness you may have used will have one. Hope this helps.

Ford factory in dash 6 disc changer/radio


I have had the same problem with my Ford CD player, if you unhook the battery and let the entire system reset itself for approximately 10 min. or so and then rehook the battery and the CD that is stuck will either come out automatically or when you push eject. If you have not let the system off the battery long enough it does not work. Trust me I have had to do this more times than I can count.

Jensen head unit VM9311TS no sound from CD


Should wire HU's Power Const to Amp's Remote On. Instead you wired HU's Power Antenna to Amp's Remote On. So the stock amp got triggered only in radio mode.

No sound


It's very likely that you have a factory amplifier in the vehicle that needs to be either turned on or (preferably) bypassed to get sound to the speakers. If your vehicle is a Mustang, it's almost certain that you have a factory amp. If the factory plug includes a long, 8-pin gray plug and a small, square 8-pin plug connected to a round cable, then the amp turn-on wire is at the opposite end of the gray plug from the constant power wire. This needs to be connected to the blue/white wire on the Sony head unit for the factory amp to turn on. Otherwise, if you dig into the radio cavity a little bit, you'll find a black 8-pin connector that looks very similar to the gray connector at the back of the radio. The black connector pins are connected directly to the speakers, bypassing the factory amp.

My Emerson NR305TT will not produce sound. Turn table works, CD Player works, FM Tuner Works, everything works except no sound comes from the unit. The on switch and volume seem to work as I hear a faint...


You have one of 3 problems:1) bad solder joints in the amplifier or preamp section 2)defective output transistors/ICs in the power amp or 3)missing or incorrect voltages to the amp section. If the unit has a headphone jack plug in a headset. If you have sound then everything is OK thru the preamp section and your problem is in the power amp. Any competent repair shop should be able to solve this one easily.
