Second battery needed in this application?

[cyber256 10+ year member]

I'm going to be running an Orion 8004 (400w) and 2500D(~2500w) so a grand total of around 2900. I've wired it using 1/0 from the battery to the trunk from there to a 4 gauge dist block. I had a 200amp alt sent to me from Dominick and I'm looking at getting a yellow top. Looking at this do you think a second battery would be required or should I be alright with what I have / plan to do. Thanks for the insight

The extra battery would help you the most if you listen with the engine off a lot. Also if you do get a battery use an isolator to prevent ur starter battery from draining.

No, I never listen to my stereo with the engine off. Whenever I do show it to someone new and they want to listen to it I simple start up my car for a couple of minutes then shut it off when I'm done.
