Trying to use my Active sub with active monitors

Hi all,
My power amp has blown, so I'll be getting some near gear, and was hoping to be able to use my sub in my new setup.
At the moment, it's
Audio interface (Which needs to be replaced as not working with Windows 10) ---> Power amp ----> Subwoofer (PSB Image subsonic 6) -> Tannoy reaveals PASSIVE monitors.

So I'm going to be changing the audio interface to most likely
Focusrite Scarlett 18i20 3rd Gen

Subwoofer issues

So ive had this issue with my subbwoofer that its randomly stops sending out any sound.

it can be dead for a day or two and then suddenly just starts working again.

Something strange that ive discovered is that it often dies when it gets a lot of bas thru the input. even stranger is when i put on some music with much bass and crank the volume it can make it start again. like a defibrillator can both kill and start a heart.

its blue sky monitors 2.1
tested with different soundcards & computers.

Best Regards Mattias

Please help me cross over the subwoofers

This is not strictly a monitoring or recording question but I am having difficulty finding a good place to ask this question since most of the forums I found seem to focus on recording and mixing rather than live sound.

I have begun mixing live sound for a band sort of at random because the drummer cannot run his gear while performing. I stepped in at his house party to cut the feedback and got nominated/appointed sound person despite my hearing issues and tangential background because there is no one else better qualified.

How to solve rumbling on the stage caused by Subs?

Hello experts,

Jarjar here. Misa confused about Subs causing rumble on the stage.
I worked as stage hand to a concert last week. They had problems with this rumbling movement caused by the subs. The subs were positioned in front of the stage, piled in 6 pairs, so there were 12 subs in total. But the vibration the subs caused was annoying for the musicians on stage.
