Are both of those speakers in the door?  If so you might check to see if they have been disconnected.  I've seen several where they've had work done on the door or the window and the speakers were not hooked back up when the work was finished.Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

Your car has an amp under the rear deck. There is a dark green and light green wire in cavity A7 & A8. These are the pass front speaker outputs. You can measure them for impedance. You should get a reading somewhere between 2-4 ohms. The tweeter has a capacitor on it, so it won't show up when you measure it. There is an intermediuate plug inside the car in the pass kick panel. It has all the wires that go into the RF door.sparky

There are capacitors on the board of the amp that have leaked onto the circuit board. This is a very common problem. The fluid is acidic and eats away at the traces on the board. Depending on whether the fluid has gotten underneath the Chips on the board, determines the complexity of the repair. You can tell which of the caps have leaked by looking at the solder connections on the board. Shiny solder = not leaking cap. Dull looking connections with a black area around the connections = leaking cap. The caps will have to be removed, the board cleaned, traces repaired if any have been eaten through. If the black grunge appears to have gotten under any of the Integrated curcuits on the board, they will need to be removed to clean the board. Be careful when removing, I have recently learned that the ICs are heat sensitive. I had trouble removing one, had to apply heat a bit longer than the other ones, and that channel did not work after the repair. If you do have to remove the chip or chips, before you reinsert them, I take some acetone in a spray bottle, lightly coat the entire amp, I did say LIGHTLY and then place the amp on concrete and using a long lighter, ignite the board. Do not let it burn more than 15 seconds at a time. I do this a couple of times. The heat seems to break up the corrosion that can not be seen or removed. Acetone is a very flammable substance. You must use some sort of sprayer to coat the board. If you have no sprayer, do not pour acetone on the board and light it. There will be too much acetone and not easy to get the fire under control.
