Battery Situation

[masonsatt]

So I just bought a XS XP 3000 (120 ah)(3000 max amps) and I was wondering when I buy a second one for this 3,400 watt system should I replace it with stock one or just put it in the back with the other battery? What do you guys think is the best.. I already have 270 alt and big 3. (Side note) should I get another xs xp 3000 or can I save some money and just get xs xp 2000 (80 ah) (max amps 2000)

i would go with another xp3000

how old is the one you have now??

I just bought it. Like my system isn't done fully yet. Do you recommend putting the second one in the back or putting it under the hood?

If the one under the hood is lead acid replace it with an agm battery. If it's already an agm just add to the back.

Closest to amp...

you doing one up front and one in rear??

Would it be better to just replace the stock battery that my car comes with? Or should I just add on to my other battery in the back? Will I still be able to run my car and my system with just two XS Power XP 3000s?

like dbjunior said, if the front is a lead acid, replace it with an agm

Will my car still be able to run and work my 3,400 watt system with just those two batteries?
