Looking for ideas on upgrading Bose factory system . So far research came back there’s no point to upgrade the factory speakers without replacing the factory amp? Or replace the speakers with 2 ohm. Help me out with some of your set up. I love music and that set up isn’t going to work. I do have a 10 inch Alpine subwoofer already and a mono amplifier. I was told to use a line converter and tap into rear speakers.

 

Get good set of components and 5 channel amp to power them
