Yes, it is designed to allow this per Daniel at O+. That said, if at all you can find a way to afford it from the get go, I would do it as it is sort of a PITA to mount and dismount that amp bracket under the passenger seat and would prefer to do it all at once the first time. Also as someone who owns the solution with both I can guarantee you the second amp is worth it.

OEM Audio + also advised me that the future 2nd sub option will be plug and play to the existing system but would be better off starting with the dedicated amp. I'm assuming the 2nd sub will use it for power.
