Double Precision bass bridge pickup?

I have decided to to turn my squier p bass into a double precision bass. I have been told to use a higher output pickup in the bridge, and to reverse the location of the bass and treble coils. My neck pickup is a Bill Lawrence Wilde P-46 (awesome sounding p pickup btw). The p-46 replaced a Dimarzio model p, which I am deciding to use as the bridge pickup. I originally replaced this pickup because of the high output causing my amp to clip. Through many hours of reading talkbass threads I hear many wire dimarzio pickups in parallel to omit this issue. How would this work in the bridge position? Should I keep the pickup wired in series? I'm using a rotary switch as a pickup selector. Advice would be great thanks
