Pioneer DEH-6900UB e46 BMW. Head unit has power and is working. No sound. Help?
Hi nick, there could be a problem with the unit wiring or with the speakers connected to the unit. Firstly Have your unit independantely bench tested, if all is okay then you know the problem is with your spk wiring or with the speakers.
If there are any speakers that you know that are not working, then isolate them and recheck the sound.
if the unit is found to be faulty then best to hand it to a repair technician.

How can I fix my 900 watt Pioneer amp? The lpf switch has broken off and no sound comes out of the speakers. Is there any way I can fix it myself?
it appears to be a slide switch having been operated with a screw driver. The PCB has some damage, but if it is just a single sided board it can probably be fixed. The first thing is finding a switch.
I am guessing a PC Mount DPDT slide switch. You can find those in a lot of places. But they come in different physical sizes so you would have to apply the measurements to your search. That one appears to have a metal case with 4 corner tabs. You may or may not need that. Aliexpress may be a good place to look as Digikey or Mouser may cost more in shipping. If the circuit is also torn up, you will need to carefully repair that. The holes need to be cleaned out first to allow mounting. If you don't know how to solder, you will have to learn and practice otherwise you may make it unrepairable.
