Nano amp and soundcard question
1/ I have this supplementary amp:
What would happen if I sent it 5v? Would it operate at a reduced wattage or not at all?
2/ How much does a soundcard or external USB sound device really affect the quality of music in the car? Or is it the particular audio drivers that affect the sound? I'm getting that light static/garbled/electric sound(hope that makes sense). It kind of goes away after its been playing for a while, but I'm wondering if an external small USB soundcard/device would correct that.
