how do i fix this problem with my speakers everything else is working fine just no sound coming out my speakers and they where working fine with the factory radio
I'm pretty sure that there is no switched power in that harness. Check the pin on the factory harness with the red one on your radio harness. If there isn't a pin there then you need to find switched power somewhere within the vehicle. Your best bet is probably the ignition or accessory wire in your ignition harness. I don't think I've ever found a switched power fuse with enough amperage capability in a BMW.
