It is likely the external audio amplifier problem: one possible cause
 
But it could also be the shorting of the two speaker wires somewhere between the Audio Amplifier and the speaker in question. When the speaker wires are shorted, you, for sure, lose that channel. But in some case, you would lose all 4 channels. You can check the shorting of the speaker wires/ Amp outputs by probing the speaker connectors (after removing the speaker from the connector) using an Ohm meter.
 
Another possibility is the broken speaker wire(s) or connection problem. Checking for broken wire is harder since you have to probe at both ends (speaker end and the Audio Amplifier end). But indirectly, you could check the DC voltage at each wire (again with the speaker taken out). At each wire, you should measure something around 6V - 8V (depending on the battery voltage. This is normally 1/2 BATTERY voltage). Broken wire has no voltage at all or some voltage out of range (13V if it is shorted to BATTERY).
 
Sometime it could be the radio itself is at fault (connection problem at radio side, blown one audio driver inside the radio)

#1529 of 1569 2008 Impala Radio Screen Scrolling by don8455

Mar 17, 2008 (5:43 pm)

I was wondering if there was a way that I could get the song title and artist to scroll across my screen when the XM radio is on. As of right now when I press the information (i) button on the top left I can choose to show only one of them. I don't know if I imagined it but I thought they did scroll when I first got the car (before I started experimenting with the buttons).

I have a 2007 Impala with about 13,000 miles on it an am on my third radio. The prievious radios just went dead. Dealer, aren't they always so helpful?, said the problem was the radio and replaced it twice. The last new radio was two weeks ago and this one is already starting to not work. Symptoms are no sound, period. Sometimes it will start working then go dead again. Dealer said they cannot fix it until I bring it in with the radio not working. Help.

See if you have an amp in the trunk between the speakers. This is probably the problem. Tell the dealers to check it, or send it out to a radio shop.

Could you share with us what the fix was?

The "Black Tie" stereos do not offer XM title scrolling. If you tune to an RDS FM station, you'll notice that the information from the FM station will scroll. This may be what you remember seeing. I researched in great detail after first purchasing my car. I had ASSUMED it would scroll since the earlier models' stereos scrolled the information but it simply isn't a capability designed into the new stereos.

There is a TSB regarding the amplifiers in the 2006 Impala. I believe it was fixed at the factory later in the model year run and as far as I know, didn't affect subsequent model years. However, the actual fix was to replace the amp between the speakers on the read deck (visible from the trunk) and to reprogram the radio's head unit. If I remember correctly, the newer amp has "Bose" molded into the metal casing (whereas I don't think the old one did).
 
As I stated in the earlier post, the hiss was reduced but it's still very noticeable by someone with an "ear" for it. I had been wanting to compare my car with a newer one ever since the "fix" came out but wasn't able to until this past Christmas. My sister bought an '07 LTZ and it has the exact same hiss as mine. So, mine is as good as it gets, I believe, which isn't saying a lot.
 
If you suspect you have the old amp in your car, take a look at it and describe it here. I also think the heat fins on the new amp run diagonal whereas the old amps fins ran inline with the sides of the casing. I'll go look at mine again if need be.
 
Good luck and keep us posted!
