2021 Ram Classic audio upgrade issue?

[Dale D]

I am wanting to upgrade my basic 5" Unconnect 3 system by adding an amp and speakers. The installer said this radio is designed to read/sense the impedence of the connected speakers. That if we break that connection by adding an amp in the chain, the radio would not produce sound to the amp. He said it would take a module that basically would trick the radio into sensing the speakers are still connected at a cost of $300. This sounds like BS to me. Any insight would be appreciated.

Yes you do need module that will bypass the factory amp and noise cancellation.. not sure what the price actually was for mine. I don’t think the part was $300
