My girlfriends son is a Marine over in afganistan,. he is coming home in October, so I grabbed his truck to do matience, when I turned on radio only tweeters worked, no door or rear speakers.
It is a 2008 1500 4 door.
It dosent have the fancy bells and whistles, just a am/fm CD player.

So far I have checked the fuses by the drivers door and under hood, all fuses are good.

ANY help would be great. His mom has been driving in it periodically, the last two weeeks it just sat. She feels she did something wrong.
I was a GM Mechanic up until 04, but IM not a tech, im a parts changing man.

Have you checked to speaker output on the radio,i.e. balance, fade ect.?

 

no, but the amps are not turning on. I found another thread stating others had the same issues and hit bumps and it comes back on, so im gonna have a friend run TSB'S Tuesday when he goes into work, he works at a GM dealer

 

I'd check the speaker settings. Not sure that the amp would come on if the woofers were switched off. I dunno, check that first.

 

well its nto the spkr settings, i checked all the basics, as i said prior, i was a GM mechanic 14 yrs, so the easy stuff was checked, even drank me a few beers doing it-lol

 

Well thats obvious. You could have posted what you did, the "basics" are as what? Not knowing, in troubleshooting anything it's always Keep It Simple Stupid.

 

as stated earlier, I checked the fuses, both boxes, I also checked for power at amps, NONE.
So the basics are covered-lol

 

Sledheadred,

Keep us updated. Let us know what your friend at the dealership finds. I hope this works out for you.
