hi all

I want to hook up the second battery for my car audio system.I want to know how to install it?I read many topic about how to install but I've question about the isolator

What does the isolator do for adding the second battery?
every one in my country said don't need to use the isolator and just install the battery in parallel mode.

I want to tell me all about the isolator in this situation for my car audio and tell me how to hook up!

thanks

You don't need an isolator. It's really easy to connect a battery, all you do is connect all the positives to each other and all the negatives/grounds to each other.
