Have all the subs play LFE and crossover signals unless your room leads bass to be highly localizable.
Mad a simple test, only have the rear subs turned on and play a test tone at the crossover frequency, if you can tell it’s coming from behind you, then either lower the crossover point or do what you described initially. However, I would say the benefit of quad subs playing the same signal trumps slight localizable benefits.
