Do I need a HO alternator?

[Rosco420i]

I am currently running a 6000w amp hooked up to an 18" re audio sub, as well as a 2600w 6 channel to my speakers. I have had everything wired from my car's stock battery to a 600w battery in my trunk for the past 2 years. My external battery has been continuing to give a signal after I turn my car off, so I bought a slightly bigger battery to replace both of mine. The one I got is an xs d6500 3900amp. I'm just wondering if my stock set up will be able to run it. I think my stock alternator is 110amps. Input is much appreciated

God yes. And do the big 3.

What brand amps are those? I'm actually surprised your "stock" electrical didn't choke out because it's not enough.

HaHa yeah I don't know how the hell it runs it I know the car audio battery I have is way weaker than I need. The 6000 is an autotek and the 6 channel is a rockville marine amp. My lights still dim when I hammer down on it but I never had any electrical problems besides than until now. I was doing some fiddling with the new battery, got it working somewhat but it made my car run like ****, like it could barely stay charged. Figured it was my alternator. So I put that on hold and put my old battery back in and now my car barely starts, it starts eventually everytime but it has a really hard time doing it. What could that be?

Also I haven't done big 3 yet but I do have all 4 ga to my amps and the ground on my battery. I just received a bunch of 0 ga wire and bigger inline fuse, I'm just gonna redo it all in 0 and see if my car can run this new battery.
