The two orange wires are for the dimmer which your aftermarket HU may not have (most $200 to $250 and up models do). The extra blue wire, which I am assuming is coming from the aftermarket HU wiring harness is for an amp. If it is coming from the Metra wiring harness then it is the antenna booster (This is from memory so I may have that wrong but I know for sure the blue wire is for the amp). These wires have nothing to do with the sound so there may be a problem with the HU or possibly the wiring harness. Hate to say this but from researching the Metra harness, I have seen that these harnesses have had problems. I have not found any specifics (read this on j body and s-10 forums) but I would not think that it would have anything to do with the sound.

The only thing I can say is make sure you have all the wires right, put in a cd, and mess with the volume, fader, and balance again. Maybe someone else will have some ideas.
