Sounds like you have a speaker out or disconnected. I would 1st pull the lf speaker and inspect the connections and if they look good you can put a small AA 9volt battery across the terminals of the speake (with it disconnected from the stereo) and see if the speaker pops if it does then you need to go to the radio and pull it out and check the wiring behind it for the LF and see if it is hooked up. If it is and all looks good the next thing you can do is swap the speaker outputs and see if the RF woorks on the LF etc... if there is still no sound on lf then it has to be the wiring in the car . Let me know if you have any more Questions! I dont know if the front dash speaker is even hooked up, do you?
