Hi Markus,
The concern I described in my previous post does not apply to the connection arrangement you've indicated, since you are connecting the sub at line level (in other words, from a preamp output of the INT-150), rather than at speaker level (in other words, from the amp's speaker output terminals).
However, if I understand correctly you are using a single sub, and just providing it with a signal corresponding to the right channel. If so, I would expect that you would get somewhat better sonics by connecting the left channel unbalanced preamp output signal of the INT-150 to the left channel unbalanced input of the sub, in addition to connecting the right channel as you are doing.
If you do that, keep in mind of course that you would have to reduce the setting of the sub's level control a little, to maintain proper balance with the main speakers.
Best regards,
