I think Marc's answer is helpful, but I wanted to add a bit more. With the audio interface connected to the Peterson, have you tried increasing the audio interface volume of the channels going to the Peterson? I wouldn't adjust the Peterson gain or output volume. However, if you have maxed the volume on the interface and Hauptwerk and you don't hear anything, or it is still very quiet, then the signal going to the Peterson isn't loud enough.
If you don't want to adjust the settings on the Peterson amplifier, you can get an amplifier, and position it between the audio interface and the Peterson. Just be careful you start at low amplification and increase very gradually, so you don't burn out the Peterson amplifier.
If you get a loud enough signal, but you get a lot of distortion, then it is possible the balance of gain/volume out is off. Usually you get distortion if your gain is really high, but volume out too low, or gain really low, volume out too high in proportion. I usually start with gain fairly low, then increase volume gradually. If unsatisfactory results, decrease volume, increase gain a bit, then try increasing volume gradually again. Repeat until you get the sound you want, slowly increasing gain.
Could be some other problem though. An important consideration is low/high frequencies. Depending on the subwoofer, sometimes you need a filter (can't remember if it is low pass or high pass), to make it sound right. For instance, if the subwoofer doesn't reproduce high frequencies well. However, if you cut out the high frequencies, you need something else to play them (other speakers in the room), otherwise it will sound strange. If you're sending a mix down with no filtering to the Peterson, you may want to try a filter, in case the strange sounds are the poorly rendered high frequencies. If you're sending it with a filter, but don't have other speakers covering the high frequencies, add speakers covering the high frequencies. If you have speakers covering the high frequencies and are filtering the input to the Peterson, try taking the filter off and see what happens. At least then you'll know how the Peterson handles high frequencies fed to it.
Also as Marc said, adjusting the volume in Hauptwerk in addition to the above may be worth a try. The Hauptwerk volume would act as a gain for the system though, so make sure it isn't too high in proportion to the other settings.
