Used to be that way for me with the middle PUP.
Then I followed some advice and installed a Dimarzio HS-2 (you can get one cheap 2nd hand, nobody loves them anymore). Wire it with just the top coil working, and you've got one of the best strat sounds around. Unlike a side-by-side humbucker, when you split a stacked PUP, it increases in output. Mine reads 8.2, plenty hot in that position.
