Will kit power saddlebag speakers and fairing lower speakers?

I would like to add Boom! Audio Stage I Saddlebag Speaker Kit (76000489A) and the Boom! Audio Stage I/II Fairing Lower Speaker Kit (76000660) to my 2016 Road Glide Ultra Limited CVO. Is this kit all I need to power the four speakers or do I need to add additional equipment?
Asked by: Eholguin12
Going to answer my own question here. I added the Boom! Audio Stage I Saddlebag Speaker Kit (76000489A) and the Boom! Audio Stage I/II Fairing Lower Speaker Kit (76000660) to my 2016 Road Glide Ultra CVO. This kit WAS all I needed to power the extra four speakers. I did purchase matching separate speaker lids (ruby red) for the saddle bag speakers. Local HD dealership (Barnett HD) installed everything so a total of eight speakers (four stock stage 1 and the four additional) sound awesome!

Part Number 76000280 Boom! Audio Stage I Speaker Expansion Kit - Saddlebag Mounted

Is this the same hardware as: 76000277A Boom! Audio Amplifier and 76000584 Boom! Audio Stage II Saddlebag Speaker Installation Kit for $50 less the two parts numbers separate ...
Asked by: OOHank
Hi OOHank, No, the Boom! Audio Stage I Speaker Expansion Kit (P/N 76000280) is not the same hardware as the Boom! Audio Amplifier (P/N 76000277A) and the Boom! Audio Stage II Saddlebag Speaker Installation Kit (P/N 76000584). While most of the parts in these kits are the same, there are specific components in each kit that help differentiate them from one another. Thank you for your question, FXS78

Boom! Audio Stage I Road Glide Bagger Kit

Do I need to add this to my Stage 1 Bagger Kit when I added my saddle bag speakers, or will the amp that I purchased with my Boom! Audio Stage I Road Glide Bagger Kit - 2-Speaker run my saddle bag speakers with enough power?
Asked by: sidetech
Hello Sidetech, PN 76000587 will also power the Boom Audio saddlebag speaker kit. So you will not need to purchase a separate Amp for them. Thank you!

Is this the only amp I need ?

I just added lower faring speakers to my 2014 street glide special and now I want to add saddle bag speakers. Is this the only amp I need or do I need the under faring amp as well? I will have 6 speakers total.
Asked by: John70
Hi John70, Yes, this amp kit will allow you to have 3 pair of speakers. You do not need another amp with your setup. Thank you
