Sounds like you might have your wires backwards on one of the coils? They will fight each other and the driver won't move.

Bro... you check it with a DMM yet?

Nah i cant figure out which setting to put it on

Even at that why would each coil work seperately but not bridged

Run each coil to a channel on the amp and see if that fixes it.
