2000 LS Speaker trouble

Allright Ill be the first one to admit that being a .50 cal gunner in Iraq has left me with terrible hearing but I know for a fact that the only speaker that works on my driver's side is the one in the drivers door. The drivers side backseat speaker and the speaker on the driver's side dash dont work at all. No sound whatsoever. Anybody got any ideas?

ok, i'll bite...

new speakers?

I have a 98. Speakers went out one by one. Had to replace them all. Wasnt too hard. Good luck. And Thank You for Supporting Our Country.
