2019 25SC tower speaker install

[cvx16]

Hey All - I have a 2019 25SC with the Premium Sound pkg, including:
- Rockford Fosgate Hide-Away unit (presumably PMX-5CAN, since the manual for this came with my boat)
- Rockford Fosgate PMX-1R remotes at helm and transom
- JL Audio M800/8v2 amp powering 3 pairs of JL Audio speakers
- JL Audio M600/1 amp powering single JL Audio sub
- No tower speakers, but tower appears to be pre-wired

I'm planning to add the tower speakers now with:
- JL Audio M400/4 amp
- JL Audio M6-880 (1-pair)

I think my M800 amp is already wired to power the tower speakers, but I need to trace all the inputs/outputs to be sure. Even if it is, I still plan to add the M400/4 for the towers.

One thing I'm trying to find right now is where the hide-away unit is located. The amps are located forward of the helm, under the port side bow seating. There is quite a bit of wiring under the helm, but I do not see the hide-away stereo unit. It appears the stereo wiring the runs aft, along the port side. My next step is to pull everything out from the stern seating hatch (my boat is outboard powered, so I have a cavernous storage hatch under the stern seating) and see if it's hidden in there.

So before I get into the overall writeup of how this project goes and the finished product, does anyone know where the location is of the RF hide-away unit in a 25SC?

Thanks!

My bad somehow missing this thread before. I thought I had looked through everything already, but on another look, found this thread and it appears to answer my question exactly.

Next step is to determine if I need to run new dedicated power for the new M400/4 amp or us the power/ground already there for the 2 other amps. Then I need to see about if I want to rerun wires to the tower for the speakers. Not sure what gauge they ran for these yet.

I would run separate power to each amp, along with an inline fuse. Unless of course you are already over killed with your power and ground wires. To be safe, run separate.
