    Im planning to install this magnetic PU into my acoustic bass, how should i route the cable?
    I prefer to avoid drilling additional holes.
    I just don want unnecessary cables hanging around.

    Historically people used pickguards for this purpose.

    If you do the pickguard thing you have to be very careful if you mount the jack there as it will be fragile. Also, think about how you are going to ground it.

    The jack wont be a problem, im gonna replace the already existed, terrible sounding piezo. it also has way less feedback and sound more natural with the magnetic PU

    The pickguard is used to hold electronics and hide cables, not as an anchor for the jack.

    why does the piezo sound "terrible"? is there a preamp inside the bass (powered by a battery?)

    if not then there's your problem! bridge piezos without preamps sound yes, terrible; weak output and no low end. put a proper piezo preamp in there and the stock pickup will be big, loud and deep-sounding.

    It has a preamp with a fresh battery, the problem is it has massive feedback even at low practice loudness because the tailpiece

    OK so it's not an impedance issue but what makes you think the tailpiece is the problem?

    if it's that you're getting excess rumble and noise from it vibrating then the simple solution is to stuff some cloth or foam up under there to immobilize it

    Well, even with foam under the tailpiece its way more feedback sensitive, and sounds less natural
