The easiest might be to buy a replacement (such as here) or a universal remote that can be programmed to control the system.

Otherwise you will likely need to dig into the system's electronics, for which there may be no information available.

If only switching on the subwoofer, which I am GUESSING is a separate package, then it should not be very complex. But usually a remote has a bunch of functions.
Probably we would need a circuit schematic to see just what will need to be switched. If you are REALLY LUCKY there might be an actual electricalmechanical relay switching on the power. More likely, not.

The one picture shows the bottom of a PCB, the other picture does not seem to be related to this discussion.
So now for questions about the subwoofer package. How does the subwoofer connect to the rest of the system?? Are you able to operate the rest of the system without the subwoofer being switched on??

The reason I ask is because I have seen a few speaker system packages where ALL of the amplifiers are inside the subwoofer housing, and the other speakers are just speakers in boxes, with NO INTERNAL ELECTRONICS. There was a remote assembly with control knobs attached to one of the speakers. Not by any means a traditional speaker system.

Okay this is what I found on YouTube hopefully it will give you some direction to give me guidance

The system is just three speaker

You don’t need a different account when using your phone. You can use the same account on multiple devices.
Yeah i know but i use different devices so therefor they have different emails so i just put sign up with google not thinking. But I will keep this one.
