I have a Quad 44 and Quad 405-2 stereo setup, however i recently obtained a B&W ASW650 Sub woofer(22kOhm Input Impedance). Now reading the technical spec for the Quad 405-2, and it says the amplifier loads the input with 20 kOhm in parallel to a 220pF capacitor. Now if i wired a Lowpass RC Filter (20Kohm & 44nF Capacitor) parallel to the amplifier to provide an output signal for the Sub woofer with a crossover frequency of 180 Hz would it effect the performance of the Quad 405-2?
Would using two lowpass filters (one for each channel) and then merging them into a mono input for the Sub woofer cause crosstalk?

on the diagram i replaced the two 20K ohm resistors with 47Kohm to create a mono signal.
