can someone explain to me have a patch this up to work???from my Synth tech E352 through the Doepfer clock divider?

A square wave from your oscillator will work well. Though some oscillators only allow one waveform to output at a time, so if you're using a triangle wave or something else... you might have issues. As far as mixing it in, there are two ways:
A) You mix both oscillators together at the output and then continue down your patching chain.
B) Your sub gets its own independent envelope generator, VCA and then is mixed in to the original signal at the very end of the signal chain.

My opinion is that it would be easier to patch in a second, independent oscillator tuned an octave or two down and just patch the same pitch CV and gate CV to it.
