The sub in the pic directly above yours is the factory unit for E53's so equipped.

No, all of the gear pictured is factory OEM DSP setup. I was just posting for illustration of exactly how many speakers the factory DSP amplifier handles for powering and tuning.

Makes for a very complicated install if going for a full one for one replacement using OEM DSP or BSW type speakers. Hopefully I wasn't confusing anyone.

You can get away with less equipment if you are using replacement speakers like Propellerhead is. You can get away with a single 4 channel amplifier if doing that. But you will lose the upper dash speakers if you don't use the head unit's amplification to handle those... and I'm not sure you'd be able to filter the frequencies enough on them, depends what type of Xover settings the head unit offers.
