How many Ohms are my subs wired up at?

Ok so i have 2 DVC 4 ohms subs and each sub is wired like this. positive from one coil to pos on the other and neg to neg and then the terminal is hooked up. it like that on each sub. and then the back (the wire that comes off the terminals to the amp) is wired like this pos from the left sub and neg from the right and its bridged on the amp and then neg to pos (terminal to terminal) and i want to know the Ohm load for each sub?
