You will have to specify a little more about the type of speakers you want to put and the brand of them.
They may be two independent pathways, that is, one route is for the normal Woofer and the other is for the tweeter that carries in the center so that you can regulate the acute without touching the rest of the sound.
But I am not very much on that subject. Normally, they are usually simpler, they carry two terminals and from there the current for the two electromagnets, the direct Woofer and the tweeter through a small condenser located on the same speaker. (Normal two -way speaker).
Anyway, in the speaker box surely puts something or says something to connect them.
All the best.
