Left side speakers not working?
 

I've got the Bose single cd AM/FM. The front & rear left side speakers play really faint. Turn the balance over to the right side and its blarring. Any ideas what would cause this? :?

loose, or pinched connection, i would have to guess....or the channels on your HU have gone out

playing faint...

electric current is only on or off... no inbetween...

had to be something with one of the controls on the radio being bad

Channel on my HU, What's A HU!

headunit=radio

So what is my next step? Should I yank it out and have it repaired, or should I replace with newer stuff? Your thoughts please.
