Re: stereo to mono box...
If the previous post seems somewhat obscure... it is a circuit diagram for a basic summing amplifier... really easy to make! 
Put a voltage divider on the output for output level and your sorted, cheap and simple
As an aside I was recently looking into building something similar to mix signals for learning songs... ended up getting this cheap line level mixer, and I installed a headphone amp inside to suit my purposes. Those mixers go for $50 at RS (IIRC) runs off pedalboard polarity 9V =
