Almost done through the buying phase of my first carputer. Just waiting for my display to come in, but quick question.
I have an aux input on my Kenwood headunit (L/R stereo). Does that mean I only get stereo sound? I remember my old Nine Inch Nails CD in my old Sony CD headunit had different audio signals to my front and back speakers. What determines if I get basic surround sound? Is it the audio track, the signal, the hardware, or all three?
