420 amp alt I would want more than 0 gauge.

You are also in an 06 Silverado. Starting in 05, that vehicle is no longer internally voltage regulated, and your voltage is controlled by the ECU. (They did that so that is has less drag and improves fuel mileage (slightly)). There are ways to program that or alter that, so you have steady voltage.

I was thinking 2 aught wire an do you think it would help if i took the secondary battery ground ran it through the ground sensor an tied the batterys in a parallel circuit, you said ways to alter the voltage how
