... I managed to get it to work! I took an AUX cable (stereo, 3 wires) and cut it in the middle, then I took an RCA cable (2 wires), cut it, and connected the two and it worked for me without disconnections.

r/bose on Reddit: Bose 900 sub compatibility?
January 23, 2022 -
Just got a 900 Soundbar because it has bass out and I like how it's made. All the reviews mentioned that you could use any sub. Now that I get it I'm reading you can only use Bose subs. I got an SVS 3000micro to pair with the 900. A sub which, in every single way, is a country mile better than the sub Bose sell. Now when I connect it, it doesn't work. I'm very angry with this outcome. I can return the SVS and get the base module 700, but it's a worse sub. Is there any way to trick the 900 into thinking I have a legit base module? I've read that some have had success with aftermarket subs. The only issue is it turns off the base for the 900. Which is what I want anyway. I'm not even sure how the sub out is even verifying what sub is connected to it. I'm just using a standard 3.5mm to rca. Do I need a balanced cable or something? Coming from the world of hifi where a sub out is a god damn sub out this really irritates me. Anyway, sorry for the rant. If anyone has got a sub to work with the 900 I'd really appreciate some help.

From my understanding the sub out only works with Bose bass modules.

When I was rewiring my home theatre recently, I noticed that there is what appears to be a 3.5mm subwoofer out on the SoundBar 900 that I didn't notice before.
Has anyone ever connected a non-Bose subwoofer using 3.5mm? I know I'll have to buy a RCA to 3.5mm adapter, but I would love to repurpose the subwoofer I have at my storage unit.

How to connect an external wired Bose subwoofer to a Bose soundbar 300? I have an old Bose subwoofer that works great but the soundbar seems like it’s made for wireless devices only. Is there an adapter. I can use - Quora
Answer (1 of 2): There should be two 3.5mm jacks on the back of the soundbar, one for ADAPTiQ, and a subwoofer output. If your old subwoofer is active and has RCA inputs, a 3.5mm stereo to dual RCA cable should work.

Hello, the Bose 900 Soundbar does work with the Subwoofer 500. I actually purchased the subwoofer 500 from bose. I bought it refurbished for $329 i think it cost. The subwoofer 500 is awesome. It is truly amazing. I keep it on 30, 40 out of 100. My son came in and said he can't believe that small subwoofer puts out that much bass. I don't know about the voltage question.
