    You could use another preamp to buffer the signal (bare bones - only need one input pair, one output pair
    - tone, balance etc. would be optional), and put a y at its output to go to the sub input.

    The XLS12 has stereo inputs, does it not? Should have mono unfiltered, mono filtered, and a stereo in/out (just don't use the out).

    it has: mono in using the built in xover...another mono in if you use an outbrd xover.............and spkr level ins and outs

    would be easy if i could go stereo to stereo

    thanks

    Two RCA female male jacks, one RCA male jack , two 10Kohm resistors, and some cable. Install the 10kohm resistors in each RCA female jack in series with the signal, then the signal after the resistors can be shorted at the male RCA connector. There you have a passive summer/isolation network. Turn up the sub a bit to overcome the level lost across the resistors, let er rip tater chip.
