Re: no sound when i connect the harness for the speakers...
Did you try to adjust the zoning function to single zone instead of dual zone. If it doesn't work then I think your output chip is fried. You can fix that by adding an external amp. You will get much better sound through a relatively cheap amp, just go with something drand named. Goodluck.

you should check the speakers next. did the speakers work prior to installing the radio? check the wire harness used to connect the radio to the car speakers that is behind the panel and make sure everything is connected correctly. please rate me if this helps. thanks and good luck!
There is 2 harness the one that you are usin wich is the main harness in the second one that normally is conected to power up tha casette deck,there it should be a pink wire conect this wire together with the red one located on the main harness,if you have any problem call me 830 488 2078 im in texas ask for Tony
No wires are touching each other on door, harness etc.? disconnect each speaker from the harness one at a time, then use a 9v battery to test the speakers, if you get a feedback from speakers then they're good and wired properly. This should't be too hard. tell me where it goes from there...
Id call you local stereo shop. I changed the head unit out in my old acura legend and had the same problem. You need to buy a special harness for the bose. Each speaker had its own amp, so i just rip it off and wired the speaker direct and trashed the amps. Now this was an older car and speakers were almost shot so no biggie. I would not recommend you doing that on and 04. Just call your local stereo shop and they should hook you up.
There is a blue and white wire from the head unit that needs to be connected to the blue wire from your car harness. This powers up a separate amplifier that provides sound to the speakers crossovers. Without doing this you will not get any sound.
