So I have many parts on order, and on the order of events is the following
1. Big 3 upgrade, much larger cables for the alternator, battery +, and ground cables
2. Upgrade from 105a to 140a alternator
3. Remove storage box and replace with Jegs battery holder
4. Run 2/0 and 2 gauge power and ground wires to batteries, alt, amp
5. Install 3kw 8 channel amp
6. Install battery isolator
7. Install new cable run for 3kw amp
8. Add a distribution block or relay in order to be able to run a large inverter off the same power wire as the amp (just not at the same time)
9. Install additional USB ports around the vehicle for phone/tablet charging purposes for passengers in 2nd/3rd row
10. Install USB charge ports, 12v socket, and voltage gauge in rear jack storage box
11. Install new 6x9 speakers to replace 4x10s in rear pillars
12. Install 6.5 midbass drivers in rear doors to match the same in front doors
I decided to do a smaller alternator upgrade than I had originally planned, the 3kw amp runs more like 1200w RMS at 4owm and with the second battery I should be ok with 140amps, though that may kill the alternators brushes a bit faster, Either way I really cant go wrong for $40, and if it dies I will just rebuild it or do a bigger upgrade
All of the cable I am using will be 2 or 2/0 gauge welding cable, it is much cheaper than buying "Audio grade" copper cabling and will accomplish the same goal. All the cable will be installed using military style battery terminals and crimp-on copper lugs, all the aftermarket connections will be made using these lugs rather than straight battery terminals, which should provide a far cleaner finished product and a better expandability if I ever need to run more wires
The amp will go under the passenger seat and is cooled with an added 12v computer fan, of which I may add another.
Will try to post more info and pictures as I move forward, hopefully I can finish this list in the next few months
