Here is how it can be wired with two 4ohm dvc subs for a 4 ohm load on the amp. This will be a safe 4 ohm bridged load for your amp. This will supply each sub with 275 watts since you have 550 watts produced by your amp on a bridged 4 ohm load. The total output will be divided between the two subs to find out what each one is receiving.

4 ohms bridged is 550 watts which is 275 for each of your subs.
