I want to use my boom box as an amplifier (i.e. I want to add an external input). I've figured out where in the internals of the boom box to put the signal, but I don't know what to do for impedance matching. The source (drum machine) has 1/4'' line outputs and headphone output. I presume I need to put a resistor across the source and then couple it with two capacitors to ground and the boom box guts. Can anyone tell me if this will work, and if so what values to use?
