Ok. Blue is usually used to turn on an external amp. Apparently your car came with 2 stereo options. I have attached schematics for both. You can check your speakers with a AA/AAA battery. Attach wires to the speaker terminals, trying to pay attention to polarity (positive will sometimes have either a + or a red mark by it). Hold the negative wire to the negative side of the battery, and, while paying attention to the speaker cone, tap the other wire to the positive side of the battery. The cone should deflect outward and you should here a 'thunk'. Yes? Good speaker. No? Hold memorial services for it. I'm guessing the speakers aren't hooked up right or they came loose somewhere.
