SR+ Premium Audio Upgrade

I recently bought a speaker harness from basenor on Amazon to enable the extra speakers for my model 3. Being that my car is a later production I do not have the rear speaker deck and being that it is SR+ I also lack a the rear amp/subwoofer.

Installing the rear speakers seems like it would be easy work as I would just need to remove the shelf, add full range speakers, install an amp and wire it up. My question is how would I go about adding a subwoofer? Would that require an additional amp or can I just use the one installed for the rear speakers? I am planning on just ordering the OEM sub to mount into the trunk.

Would this thread help you?

Would this thread help you?

Yes! It looks like the OP in that thread used a single amp. Thank you!
