1) I wonder if inside the receiver, you have the sub outputs set as LFE only? (If your receiver has a setting like that). LFE=Low Frequency Effects, which is a special channel for exactly that, not for "normal" bass more like for explosions, and it may not have much content a lot of the time. Out of music sources, maybe none.
2) Turn off YPAO. Set the speakers all to LARGE. Turn the volume way down, power everything down, disconnect the RCAs from "sub" and connect ONE SUB to "front"; rotate the subwoofers crossover to 150, turn on and slowly turn up volume. If you don't hear a lot of sound, something is wrong with that sub. Repeat for the other. Why one at a time? In case they are somehow electrically or acoustically out-of-phase and canceling each other out. Why "front"? To avoid crossover issues.
2b) Actually I would plug a totally different source directly into the sub. Turn sub OFF. Set the sub volume all the way down and connect direct to disc player or cable box or phone. Turn sub ON and turn the gain up slowly.
2c) In either of these scenarios, with 150 Hz crossover you'll still hear some voice and so on.
3) They are 8" subs...DT is a very good company, but physics says don't expect huge thunderous bass out of 8" cones. I don't think that's your issue, but if the crossovers are set very low and your room big blah blah blah maybe there just really isn't much output down there.
