Hey everyone! I have a 2020 Ecosport with a B&O audio system and I want to add on a JL audio 10W6 and a 2000 watt amp to the factory subwoofer system. I saw a thread about adding in a 4 channel amp and another amp for add on subwoofer. I want to only do the subwoofer amp add on to my B&O sound system, is that possible or no? If it is, do I use the same adapters as the ones in the thread about adding in a 4 channel and sub amps?
