I had a JVC CD player installed in my car in June 07 by a auto-electrician. Everything worked perfectly untill the car went for a service and they worked on the clutch (detaching the - terminal of the battery). After I got the car back, i couldnt get any sound...? The whole system works perfectly ( switch on, load cd's, play them, search radio stasions, skip songs, adjust volume) BUT NO SOUND AT ALL. I removed the whole system to check all the connections at the back ( the atenna, i think it is, and the little box carrying all the different wires). They all seem perfectly attached. We stay in Bonnievale, making it diffucult for me to reach a pro!! Could u please guide me to what might possibly be faulty?

try to find the reset a little indent on the face or hole when you remove the face and push in for 2 to 3 secs with a pen or paper clip. Then try your cd again. Still dont work check to see if you have another cd jammed inside and your trying to put two cds at once.
Ok for your no sound problem. a bad speaker, short speaker (one 1 speaker shorts out all will not work cause the radio is in a protective mode), factory amp needs to be turned on, bose system or amplified system in car needs to be rewired to bypass factory amp), buy special car harness to make factory amp compatible with aftermarket radio, late ford models the back speakers are crisscrossed.
Next time please give car info and type of system you got in it so I could narrow down the possible problems a little bit easier.
you have one speaker that has a short, a good way to find it quick is turn radio off and on if any of them pop even the slightest that is where your problem is...if you dont hear a pop check that all wires are not touching a ground somewhere this send the unit into protection, just one speaker or wire will do this .it keeps the radio from burning up...
You most likely have a shorted or damaged speaker, which is causing the internal amp chip to shut down (but does not affect the preamp outputs). A test you can do is to fade to one speaker at a time and turn it up to se if it shuts down. Repeat with each speaker until you find the one that causes the fault. Then replace it.
You should test all of the speaker wires by putting the negatieve wire (the ones with the stripes) to the negative end of a AA battery and the positive wire to the positive end. You will hear a light, high pitched noise if the speakers are working correctly.
