Firt you clean the subwoofer with cleaner after that, check the subwoofer srrounding, no electrical wire ,mobile phone & electrical operated items is near ur subwoofer.
1. Do not use maximum volume of subwoofer.
2. Use only 65-85% volume of your sub woofer.

It's no clear what you mean by "I had to change the STK", but if that means you have somehow defeated the fusing or place a larger fuse than it requires then STOP and shut it off. You might be risking a fire or more serious damage to the amp.
I would recommend you find a hands-on tech to look at it.
If you have resolved the fuse problem and now just have low subwoofer volume, you might want to track it back to the source and ITS subwoofer volume setting. There IS a volume level control on the sub, too. Turn it up.
take an ohm meter and remove wires from speaker...put meter in the ohms position...you will put a lead on each of the terminals of the speaker...you should have a reading of 2, 4, 8 ohms....you may also try to use the continuity test, same, but there will be a beep ....this basically ensures that the coil running through the speaker is still good, as one piece, otherwise it will get no good reading and this is usually from blowing the speaker or sudden high bass sounds....
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.
I had a problem with no audio and I recently found the fix. When the
sub still worked and you turn it on you hear one relay click and then
about 5 seconds later a second relay clicks and the audio comes on. The
problem I had lies with that second relay. When you take the case apart
there are 4 circuit boards. The big board with the two big blue
capacitors is the main board. Well next to the two blue capacitors is a
blue relay. That relay had a pin that came un-soldered from the circuit
board. I re-soldered that pin and the sub works just like new. If you

you can find a free service manual that has the wiring schematics for
the amp. Hope this helps!
