Stingray is series?

I am the proud new owner of a ’97 Stingray (4 string, 3 band EQ). This is my first non-Fender bass, BTW, and I have a newbie type question.

I understand that Stingrays are wired in parallel. Is it possible to wire the pickup in series? Or better yet, install a series/parallel switch?

Thanks!

Mac.
