Tower Wiring Help Please?

07 MB B52 with stock tower. I am trying to set up wiring for 1pair of REV 10s. Can someone steer me to what wires? guage? sheathed conductor? with particular attention to entry/exit grommets from boat to tower. I am not a fan of the Neutrik plugs as they are klunky and indiscrete. Also, I do not need a disconnect. The wires will have to go out of the tower at the pivot point of the front leg and travel over the knuckle and then go back into the tower leg. (see photo of current wires)
I want the option to add LED later and perhaps a light bar or nav light also.
I have searched the forum and found these grommets made for deck wiring.

Any experience with these or a better option? I appreciate the help.

Yes, your Wet Sounds dealer can be a resource for these details. Wire gauge will depend on the amp driving the speaker, not the speaker size.

I would go ahead and wire the pods and run the wires for the LEDs now.

You pulling the wires yourself? Easy to do with wire already there. Yes grommets will make a cleaner install and help keep water from running down the wire toward your amps.

A little wire sheathing in you choice of color would clean it up as well.
