Electrical help?! new to car audio.

[slick.seal]

Sup guys pretty new here, I was just wondering if my car would run my new sound system without any electrical problems.

My car(toyota highlander 2005 stock) ran a 750watt mono amp pretty fine with just minor dimming no major problems but I'm about to get a 500 JL mono amp and a 100x4channel Alpine amp so a total of 900 amps will be running. I'm already planning on getting an optima yellow top since my battery is very old and I'm thinking of doing "the big 3" but I also heard its recommended to upgrade your alt for 1000watt systems and above but since its very close Idk what to do. I really don't wanna spend on an expensive alternator. Would a cap be good to??

What do you guys think?

Do the big 3 in 1/0 to start... Don't use an optima upfront they are way too pricey for what you get look into Deka (may sell mine) or xs power... And whoever told you you need an alt for 1000+ is a ******* lol

Ok so I guess from what I'm reading is that all I would need is a better battery and the "the big 3" upgrade? also I was looking at XS power batteries but they have many different versions. Anyone know which would be good for my system??

Thanks for the help so far guys.

I suggest a Stinger SPV44 for up front. Its a pretty good battery, i've had nothing but good things to say about them after switching from Kinetik. And they're not too pricey either, I paid $140 for mine at a local audio shop.

Also, just do the big 3, its not that hard.
