Second battery and wiring 2 locs

[sambirdthe3rd]

I have a 2018 f150, looking to keep factory head unit, not running a dsp as this is budget build. I have a t harness, skar doors, amp and subs, also going to run audio controls lgds to protect my tweeters, im curious on 3 issues.
Will my chimes and alerts be ear shattering?
I have a second battery going in, I plan to install with 0 gauge because of space but will run 3 feet of 1/0 off of the aux battery to my 2000.1, just wondering if that would work.
Also I plan to run a 4 channel loc and a 2 channel for sub. The 2 channel will be wired right before the 4 channel.
I’m just trying to make sure this will work. Looking to keep the factory sound for now, will add a dsp later.
