Since this is intermittent it's not likely a fuse blown, so I'm left to think there must be a loose wire somewhere between the console and the amplifier in the trunk. Usually the sound will come back on if I turn the engine off and then back on. I suppose that is because the vibration that is shaking the wire loose was stopped, letting it make the connection again.

all the radio and cd functions work, and all the displays as well, but intermittently no sound.


Is there a typical location for such a loose wire (to plague me) ?

Z, do you have the amplifier in the trunk? If so try moving the wire assembly that connects to it around to see if sound cuts out.

Amp is on right side of trunk. Wire harness is on its left side (toward front of car) if you were facing it.

Oh, should have asked this 1st. Does this only happen on radio? If yes, good news - it's supposed to. The radio as designed will mute when a station's signal goes low. You see, in their infinite wisdom the radio designers realized that many radio stations broadcast from several locations simultaneously. As I recall these locations each use a different frequency. The radio is designed to mute the signal and search for a better "sister" signal. When it's tough to find you get prolonged silence. This drove folks nuts, they issued a TSB with instructions to disable it.

While you can turn this off in the setup menu, i just realized you might have already tried to push different station buttons with same result. If that's true, this is moot. Only the original station is muted.

Yes, the amplifier is stacked up above the CD player. I‘ve got the Alpine System.

I seldom use the radio, so It happens when the CD function is active. But then I’ll try the radio and cassette, no audio from those inputs are either. But all the displays are lit up and functioning normally. As mentioned, this a totally random occurrence.

I’ll pull the cover off of the audio gear in the trunk in the morning and wiggle the wires and plugs. I was hoping there would be a single stand alone wire that is the typical.culprit.

Z, there's a similar post down below. No evident answers for you, but there is one guy who had a swinging open on the trigger lead for the amp. When this goes open, it will make the system silent.

I just scrutinized the 2003 electrical book, they do not identify this wire by name or by color. Frustrating.

Every car stereo system I've ever seen has a wire that runs from the head unit to the amplifier. When the head unit or radio is turned on it sends a 12volt low current signal to the amp telling it to energize. Our cars must have one too.

I guess this then begs you to wiggle the wires behind the radio to try to induce the failure after the wires in the trunk.

Not sure if you know, but there's way more access to the radio's rear than one would think. The carpet along the transmission tunnel is just stuffed up behind the console. Reach up, pull it down = easy access to rear of radio.

hope it winds up to be a simple wire connection z.

Hi Z,

did you manage to find a solution to your problem? i've checked all fuses & loose wires. im thinking this could be my Amplifier…

best regards,

I think I posted my progress somewhere in the forum, but here goes :

I had no easy way to test the amplifier, but they were so so inexpensive on eBay I just bought one on speculation for $38 (more or less).

It worked !

Be sure to check the numbers on your amp before ordering a replacement, they have to match.

Best of luck
