What would you do? The factory build options for adding 2 bow speakers, sub and amp, and 2 Wetsounds 10" tower speakers cost $3250 (2019 build prices) vs $550 for wiring and amp for tower speaker. The sub I saw in the local dealer's Makai was free air behind the dash, which I know is not ideal.

Is the tower pre-wired for speakers without ordering the $550 option?
What are the components the factory actually installs in these packages?
Is it worth it to do the factory stuff, vs adding it later? One advantage is getting the cost built into the financing.
If you were going to replicate the factory install, with maybe slightly better components, what would you use?
