Radio no sound

Can someone please help... I drive 2003 x5 3.0 and having random no sound problem with my radio. I recently had my alternator replaced and ever since then ive been getting no sound on my suv randomly will have sound then no sound. I took it back to the shop and they said that there were no other wires he thinks that would cause that when he replaced the alternator.He said that its possible that there might be a short when my alternator went bad and try to jump start it when it had a bad alternator.What can cause this? My fuses seems to be ok. Any response to shed a light is appreciated.Thanks!

need more info

"random no sound problem" ... does this mean the no sound but the radio is still powered up, or does everything shut off? no lights on radio?

define everything that actually happens

more often than not these are not relative, but coincidence

Thanks for reply but yes I get no sound and the radio is powered on and Iam able to change radio stations. It seems to go out everytime i am accelerating at over 3 rpm will no sound then come back on. One time i was getting gas when radio sound was off after getting full tank of gas, my radio started to work again. Now i woke up my radio is again has no sound.Thanks for any input.

your new alternator may possibly be putting out too much voltage as RPM increases, if it climbs outside the operating range of the amplifier it will shut off. most caraudio equipment does not like to see more than 15-16 volts

another possibility is that you have a speaker going to ground or shorting out, this would also cause amplifier shutdown.

if your charging system is normal, which is to say your alternator should put out between 13-14.5 volts when running, then I would find a reputable car stereo shop, which can be difficult.

Ok thanks for the info . I called the shop and say theyre going to check the output of the new alternator. My speakers are shots so thats a posibilty like u said.I just hope they can figure it out. Thanks again.
