Installing aftermarket head unit w/Acoustic Feedback System

[AJM511 10+ year member]

My friend has a 2001 honda prelude with the stock acoustic feedback system installed in it. He wants to put an aftermarket radio in with usb, bluetooth, etc.., but I don't know much about the stock system. There were two wiring harnesses connected to the head unit.

Is there any way to get the AFBS to work with the aftermarket radio, or is he going to have to just buy new rear speakers, and rewire everything to make it work?
