When working with low-quality acapellas extracted through an AI acapella extractor, there are a few things you can do to try and improve the quality:

1. Use noise reduction techniques: AI acapella extractors may leave some noise and artifacts in the extracted acapella, so you can use noise reduction techniques to remove some of these unwanted sounds. Tools like iZotope RX, Audacity or Adobe Audition have features that can help remove noise.

2. Use equalization (EQ): Use an EQ to help bring out the vocal frequencies and reduce any unwanted frequencies that may be present in the acapella.

3. Time alignment: Adjust the timing of the acapella to line up with the instrumental track if needed.

4. Use pitch correction: Depending on the quality of the extracted acapella, you may need to use pitch correction to fix any pitch issues.

5. Reverb and other effects: You may also want to use reverb or other effects to help blend the acapella with the instrumental track.

It's important to keep in mind that even with these techniques, the quality of the acapella may still not be ideal, so it's important to manage your expectations accordingly.
