Dual Battery Setup DIY

[Nesto1000]

go on ebay get a 25 ft spool of 0gauge bullz audio wire its 34 bucks shipped should be plenty if you want extra you can get 50ft for 50-54 bucks thats what i used, if your gonna use your radio when truck is off then id for sure get an isolator so your starting battery is seperate from your system, 1k rms shouldnt effect lights much id do big three and make sure your amp has good clean ground as well before spending money on dual bat set up

Well ima get 1/0 Ga welders wire for my truck...

Would this diagram work?
Only this uses a solenoid instead of an isolator....
