[System design/help]

If this is not the place for this can someone please point me in the right direction? I am wanting to build a system for my 2008 Chevy Tahoe. I want to build it right. I have wasted way more money trying to save money than I would have if I would of bit the bullet the first, second & third times, as I am sure a lot of us have done. I have no problem admitting I have been an idiot up to this point. With that being said, the things I am needing to know are: what type of power I’ll need, best amps for the mids, tweeters, subs, ect. I will list the equipment I currently have and the equipment I intend to install. I have never competed in any big competitions. I dont know if i will. I do want it to be ridiculously loud to most people but I also want it to be reliable. I dont want to worry about blowing it up when i crank the volume. Any help or advice is appreciated more than you can imagine. Thank you in advance.

Current set up:

2-Optima red tops under the hood 2-XS Power D4800 in the back

2-power master 245a alternators

Head unit-Kenwood DDX9707S

Front doors/a-pillar-Skar Audio xps65c components 

Pass doors- DS-18 6.5

3-Skar audio ZVX-12 D2

amps:

2-Skar SKv2-3500.D1 (strapped)

1-Skar Skv2-200.4D 

3.5”rear speakers are still factory

 

New plan:

3-Sundown zv6 12 D2

2-SALT8 or would the 12k be better for the subs?

2- SA-6.5 CS V.3 component sets (front and rear doors)

1-SALT 2000.6 (doors and rear 3.5s)

Mechman 400a alternators

SMD 8 spot anl fuse block (already have just not installed yet)

Lithium batteries? how many?

Rear 3.5 speakers-?

cable-2/0? From alts to batt/distribution block

1/0 from fuse block to amps ???

I am open to suggestions on any part of this design.

Im planning on using the Sundown SALT series amplifiers. I have one in my other truck and couldn’t be happy with it. I don’t want to lose my second row seating. That is the reason I decided to go with the 3-12s. I would like for it to be able to hit 155 i don’t think that should be a problem.  Ok after reading all this Im wondering if I just should of  said. Hey I want to build a system for a 2008 tahoe up to the c-pillars that will hit 155db+ that won’t blow too easy. LOL i would just appreciate any help anyone can give me. With all my projects and the wrong choices I’ve been making as far as what i thought would be great. I cant afford to make any more unneeded audio purchases. Thank you
