Houstonreef, my understanding is that you are correct. Most would prefer to set up the sub in the way you described (essentially bi-wiring the sub and speakers from the integrated amp speaker outputs). You will probably need to adjust the highpass filter and volume of your sub to integrate with your speakers by using a sound meter and low frequency sweep CD/mp3. Once that is properly set up, you can forget about the sub and let your integrated amp take care of volume level. Maybe others can chime in.
