Reducing strain on the electrical system

[FuzzAZ]

I drive a 2013 lancer, and it is under a very strict warranty. I want to put in a pretty big system over the next year or so, and I was wondering what the best way to reduce strain on my electrical system would be.

My alternator puts out 130A

The first install will pull 500W RMS, 1000 peak.

And the second install will pull an additional 600-700W RMS, 1400 peak.

I can't upgrade my alternator because Mitsubishi doesn't make HO alternators, and it would void my warranty to use a non-Mitsubishi part in it.

I was thinking a big battery, a second battery, a capacitor, and the big 3, but I don't knowhow much it will reduce the strain as much as delay it.

if only 1200 watts rms total then just a big battery under the hood and the big 3 ,no cap

Big 3 will help for sure. Just did it to my car and that should not effect your warrenty at all

use a capacitor.

Why no capacitor?

And what sized battery would be best?

caps do more harm than good , as far as the battery ,the biggest you can fit under the hood.i also sell bi3 kits ,if interested

If I put a large battery in the front, and my current one that I'm replacing in the back and isolate them would it help? I'm a delivery driver, so the system is going to be on for roughly 5 hours at a time.

you can do an isolator ,but not necessary ,if you do ,then the bigger battery for the system

So have the same battery up front and put a big, probably gel, battery in the back?
