Im trying to figure out how you would hook up a sub to a system that had a basic pre amp and a basic power amp combo. The preamp would typically have 4-6 inputs and a single pre amp out to the power amp, i know more modern units might have more pre amps out etc but a lot dont.
Could you hook up the sub to the tape out ? is that a valid acoustical thing to do ?
I cant think of another way because you want the sub to receive the L/R channels of a stereo system.
Anyone got any other ideas ?
