I'm getting white mouse only when i connect the two input channels. if i only use one, the audio comes out ok from the speakers.anyone know why?

Do you mean white noise? I am going to assume it was a type. If you troubleshoot both inputs as in moving the working channel from L to R and vise versa and both channels work with one wire, do the same from the source. Make sure it is not the source. Try a different device. I mean this is sort of basic troubleshooting. If you find the problem still does not go away , then you have a bad unit and you need to exchange it.

Can you somehow connect a bluetooth speaker to this amplifier or to any other hifi amplifier for that matter?

As shown in Amazon, the unit has RCA plugs for L & R inputs and four output Speaker terminals for L (+-) and R (+/-). Speakers may be connected to these output terminals. N.B. The output L and R channels may NOT share ANY terminals in common. The amplifier knows nothing about Bluetooth operations.

Where is my powersupply!?!?!

Mine didn’t come with a power supply either. I contacted amazon to correct the issue. It was a simple mix up since they sell the exact same amp, with and without the power supply. They sent a whole new amp and power supply.

can you split the wire between left and right PC speakers and hook to terminal on this amp?

If you mean pos left and pos right out of the pc and a common ground to the inputs...yes but since there is amplification from the pc you amp range of the devise might be limited and some distortion in higher volume
