Can I put humbuckers in a strat without getting new pots or a pickup selector?

I put together a strat with parts off of eBay and don't like the sound of the single coils that are in it now. I was recently at guitar center and found a set of Seymour duncans that I want to put in. If I just undid the wiring from the bridge and neck pickups and hooked up the Seymours then would I have any wiring issues?
