Fill in the missing parts I need...

[CFH]

I am trying to get this system together by spring on my 02 WS vlx... I have the main parts already just a few missing pieces.  I am doing the battery relocation and adding the amp rack to the nav area.  Ok... done.  All I really need some guidance on what size fuse I should use and distribution box for what I have.  I have the following below.

2 battery setup with perko swtich.

Precision power 900.4 for my towers(rockfords)

Precision power 900.5 for my 4 interiors(Polks db651s) and 1 sub(12 inch kicker)

So for the fuse size...from the battery to the distribution block... do I ad all the number of fuses on the amps? There's 2 per amp. 

What distribution block do you recommend? Do i need only 1 or 2 for the grounding also?  Where should I ground the amps too? the batteries?

As you can see I am not great with audio...

I am interested in what you decide to use. I have a similar setup (perko switch and ppi 900.4 under port helm) and will be adding a battery and additional ppi 900.4 this spring.

On a side note I am very close to your location.  I live on the north side of Cass lake near Dodge Park.
