Currently I have arc moto720 state 2 rf fairing and bag lid 5x7 and a sinister sound line driver rca adapter thing. I got a newer bike this week at auction 2022 street glide. No speakers but Fosgate 800x4 amp. So I’m moving my speakers and equipment over to this newer bike. Is that sinister sound device even needed or should I ditch it. I bought fairing lowers the Chinese xmt moto ones on Amazon. So I need to purchase one more pair of speakers. Also was planning on adding a fosgate bag subwoofer. My thought is arc 720 in dash running fairing speakers. And mount fosgate amp in saddle bag. And run the sub and bag lid speakers on that. Another thought is will the fairing stage 2 speaker fit in the lower fairing pod. And possibly put new speakers in upper fairing. Something like those 450 dollar hertz Kind of a lot to go over. And advise would be appreciated
