2nd Battery Added To The Trunk

[BlackRob707]

I just bought new subs and amps....now im trying to figure out how everything is suppost to be for a clean install.

I hope this is not confusing

My questions are:

What fuse do I use for the main power wire going to the 2nd batt?? 150A?

Do I have to ground the 2nd batt to the trunk???

Does everything else look fine or am I missing something?

SPECS

Batt

PPI amp The amp has two power wire inputs and two ground inputs
