your pics arent really clear, should take pics with plastic off, but ill guess the terminals are tw-, 0db, -3db -6d and the other is i think input +ve and -ve and then mids +ve and -ve
from your amp +ve -ve should go to the input +ve -ve,
your midrange speaker +ve -ve goes to the m+ m-
and from tweeter, the -ve to TW-
from tweeter +ve can go to any of the 3 terminals, 0db or -3d or -6db
u can try 0db first, if u feel its too sharp or too loud, then go to -3, and then -6 to see which suits u the best.
