If your surround processor has only one PREAMP OUTPUT (and no SUBWOOFER OUT), and you do not have an M&K High-Pass Filter or crossover, you must use a Y-connector to feed the amplifier and subwoofer. See Figure 5 above. If you have a surround sound processor with a SUBWOOFER OUTPUT jack, use it to feed the subwoofer. See Figure 3 on page 8.

Some surround processors/receivers/amps have very low output levels from their SUBWOOFER OUTPUT jacks. If you do not get enough bass when using the SUBWOOFER OUTPUT jacks on a non-THX processor, use that processor's PREAMP OUTPUT jacks instead. See Figure 5 above.
