Clarion troubleshooting Sound comes on for about one second and then nothing. Was working fine the other day.

Question moved from Office Equipment.

It is a unit with known issues!

Try pulling it out of the dash and unplugging the wiring harness for a few minutes

Disconnect all the speaker leads and then hook one speaker (a new, known to work speaker) up directly to the radio using a short (6"-12") piece of speaker wire. Does that speaker work then?

There is a stuck relay on the control board.
The control board will have to be replaced.

make sure your wirings are rated to handle the current needed by your radio. You might have a large voltage drop when it is at high volume level because it will draw lots of current. You might need to change the size of your wires to your Clarion. Check the voltage near the radio when it starts to flicker if it goes below the source voltage of 12V. hope this helps

Check to make sure exposed wires aren't grounding themselves out. I just had this problem and after 2 days of re-wiring and re-checking almost every wire I finally found the culprit. The Remote wire from my amp has become exposed and grounded itself out. Unit worked fine, same problems you are having.

lol hope you figured this out, your power muted the unit.

more info would be nice...

what did you hook it up to?

sounds like the ohm load of your speakers is incorrect and overloaded the amp,....check all your specs, i.e. max, min ohm load on stereo, and speakers,...this stuff is important and must be within the range allowed or stuff like your experiencing happens,.....it's happened to me before,.....fried my amp because i had house speakers in my van, was great for about 3 loud days,....good luck, cracklin joe,.......

Check the fuses in the fuse block under the hood. Your clock fuse and radio constant power fuse are combined in this vehicle.
