The PRS is 5 volt. When you measure it though you will almost never see anywhere near the voltage that the HU is rated for. If you have the volume all the way up and all settings maxed you may see over a volt, obviously that's not the way to run things lol.
Seems like you may have a partially blown output or something. Are any of the speaker wires bare and touching anything, I don't see why the internal amp would have any affect on the pre-outs like that, but it did for a reason. Good luck!
