I have a 2021 Pinnacle with a burning desire to pull out the Junky JBL AURA and install a small receiver amp in the same location as the AURA unit. I'm asking for suggestions and recommendations from Pinnacle Owners custom work. I would like to use the speakers in the ceiling (but put better speakers in). Marantz makes a slim-line series of receivers which I used in my Motorhome and was pleased with the result but the existing space for the AURA will have to be modified (enlarged) to accommodate it.
