How do I power all of this

[Skaraud1oguy]

I have 4500 W RMS power in for 18 inch scar subs, EVl 18 to be exact.

I have an additional 800 W RMS 4 channel powering for scar in BX 10 inch 200 RMS speakers with each speaker receiving their own channel at 200 RMS.

I also have an additional 600 W of RMS Powering for NBX6.5 inch 150 w RMS Powered by four channels each speaker receives their own channel at 150 RMS

And also another additional 400 W RMS powering 400 white super bullet tweeters with a four channel each channel being 100 W rms powering one speaker

All total out to be 6300 W of RMS. I have also purchased a 370 amp alternator for my car which I’m sure is not enough as well as 2Xs power batteries( d3400 4000w 3300 max amp)
And 2xs power sb500-34 superbanks
I need my car to be able to power about 8000 W can someone help me figure out what I can do with my alternator whether I need to or not or if there’s another way I would appreciate it I’m also going to attach files of my hand written equations.

2 HO alts, and about 3-4 batteries.

You recommend any kind of battery? I was thinking the D 3400 or even D 4700. I also would like to get some form of power capacitor to hold some power. And I’m assuming I would have to get some kind of bracket for dual alt Custom made

Skar? I would use a wall socket.

Skar isn’t that bad In their price point. The wall socket idea would be cool though.

A cap isn't necessary once the electrical is beefed up, if your electrical is strong enough.
