Also going back to my first question, would a 1/2 DIN equalizer with HiVoltage outputs, output what it's rated at (lets say 5 volts) or would it be limited to the voltage inputted into it?

I don't know. I think that would depend on the equalizer. If you're planning on buying from Crutchfield, I think they'd be able to tell you that.
