Considerable volume loss with both pickups full

Hi, i just changed pickups on my bass, its two MM style humbuckers. When i turn both my pickups on full the volume drops pretty drastically, tone is more thin then with one or another pickup soloed, and it seems that there is more high mids and treble. There wasnt this problem with old pickups, yes there was volume drop too, but hardly noticeable, it just slightly scooped some mids. New pickups have coils in paralel, old in series. Some advices about it?

 

I used this scheme:

, its from manufacturer, or how to say it (my english...), i use paralel wiring(first scheme). Picture is not in english, but green and brown goes to volume pot and rest goes to the ground, so which of this should i swap? green and brown to ground and the rest to volume pot? except shielding probably?

 

Ok, i will try it, thanks for advice.

 

Wow, done, now it works like it should... i must say i kinda liked that midrangy/trebly bright out of phase sound, but that volume drop was too much... anyway, thanks
