It seems as though the speakers wire connector may have become loose or disconnected. You will have to remove the switch cover above the Keyboard to check. Here is the typical instructions for removing it:
Before you begin any removal or installation procedures:
1. Shut down the computer. If you are unsure whether the computer is off or in hibernation, turn the computer on, and then shut it down through the operating system.
2. Disconnect all external devices connected to the computer.
3. Disconnect the power cord.
4. Remove the battery by following these steps:

the LED board cable is connected and disconnect the cable 2

SOURCE: Sony SA-VA 100 won't turn on
You can try a factory reset.
Push and hold down Dolby NR, stop and disc 7 buttons, then push power.
Otherwise it looks like $60 to $100 repair bill. These are not the most repair freindly units.

SOURCE: replacing sub speaker
I wouldn't try reinventing it by replacing the driver. Drivers and their enclosures are designed to work together. And this being a self-amplified subwoofer, there is one more piece that's electrically optimized to the rest. Don't mess with it.
Why don't you just set your receiver's individual relative speaker volume levels so the sub isn't weak by comparison to your other speakers? Weakness, as you call it, is relative.
Is your receiver properly channeling Low Frequencies to the sub? Experiment with the cutoff, too.
This problem doesn't require meatball surgery.
