New battery...

Got a yellow top... want to connect it up as a second battery...

Positive wire from the battery in the front goes to the one in the back... now I heard to get an issolater... but then from other people I heard NO! Get (insert name here) those are better.

What do you recomend...

NOW is this a dumb idea.. after I ground the battery to a NICE part of the car... would it be dumb to put the amp grounds onto the negitive of the battery because thats a ground... if so explain why.

sometimes I just have doubts and I think its acutally better to doubt my self... and ask then to not... so I ask alot of question I KNOW the answers to... just to double/tripple check.

Alright now would you say issolator or what?

Personally, if they're different kinds of batteries, I would use an isolator. But that's me.
