Need Duncan Classic Stack Wiring Help

I have an SX SPJ62 and I wanted to put a Classic Stack in the bridge position for a slightly hotter output and an end to single coil hum. I wired it as instructed on the Duncan website (white + red together and taped off, green + bare to ground, black to hot). I left the rest of the wiring for the Precision pickup and Tone alone.

My problems are as follows. If the precision pickup isn't all the way up, I get an incredibly thin sound which I assume means it's out of phase. This only happens when the bridge pickup is up all the way. Also I'm still getting a decent some hum from the bridge pickup when I'm not touching the strings.

Any ideas?

 

Bump.
