Sub out - like Stereomour?

PJ had mentioned it in the past.  There's a 249K resistor between the 0.1uF brown coupling cap and ground. You can lift the ground end, then solder in a 2.49K resistor between the free end of the 249K resistor and ground.  The subwoofer out can be taken from this node.  I would run a twisted pair of wires from ground and this node on each channel to a pair of female RCA plugs and let them hang from the bottom out the back of the amp just to test this out.

We just did this mod to a Stereomour, and it works great. I recently completed two S.E.X. 3.0 with C4S, and would like to also add subwoofer outputs to one of them. Is it a good idea to do the same thing as we did to the Stereomour? Thanks!

It should work, though you may find that the subwoofer level control will need to be adjusted when swapping between the two amps.

That's good news - thanks! In fact, I think I will add the sub outs to both of the S.E.X. amps while I am at it. On the Stereomour we used two 2-lug terminal strips and shielded 2-conductor - pretty neat and performs perfectly.
