Subwoofer speaker input

Solution
Makes and models would help.
If the integrated has a line level sub out then you could connect that safely to the speaker level input of a powered sub but you won't get any sound. The sub out is just too low. If the sub only has speaker level inputs then connect those to the speaker terminals of the amp. It can be in parallel with your speakers.
