2007 Outback Tower Speakers

[Klipper]

Hi Moomba family, I havn't posted in a long time but am still loving my Outback.

I am looking to finally upgrade from the base factory sound system to one with amps, towers and sub.

My question is around the towers. What position is best to mount the towers? I have the red-a-cage tower. There are three locations that I have come across:

1. On the flat supports between the 2 tube sections of the tower:

2. On the tube closest to the stern, with exposed wiring that goes into the tube closest to the bow.

3. On the tube closest to the bow

I know that I need to run the wires down the tower closest to the bow. Am wondering for those who have the experience and have done the install or have this type of tower, what works best?
If I mount to the supports between the tubes, can I run the wires inside the support? Is there a "hole" that goes into the downtube that I need? Same question when mounting on the tube closest to the stern.

Thanks for all the help.
