I found a good deal on two lithium Lithium LiFePO4 batteries.
id get one of these: https://www.amazon.com/gp/product/B09TWGZ37P/ref=ox_sc_act_title_1?smid=AYUFLPCBY5M3&th=1
Or 2 of these:

Amazon.com

im currently running 2 large AGM batteries, but im doing some upgrades with my amps/subs so i want to make sure my electrical will hold up,my alternator is holding its own now.

lastley do i need a battery isolator? I dont think so since everything is 12v and my system is staying at 14.2v i just dont sit and listen to my system unless the car is running.

My best goal outcome is to just put the lithium in parallel and thats it besides a GIANT fuse.

i like these a lot. they are used, but i think these would be a really nice high current switch for you, used in 12V system.
i purchased a small batch of these and i have been testing them out, they have been performing well for me on my bench setup.
I plan to run ultra-caps & headway cell setup. my alternator voltage runs 13.5V when it warmed up, 14.5V when it's cool.

"TE Connectivity EV200AAANA 500a 0-900vdc Tyco 12/24v"

I have seen these relays used in electrical vehicle applications, they are very nice.
these would work well for isolation/switching/connecting battery packs, imho.

Tell me if anyone knows,how many amps should the isolator should be?
I read on the net,which i rarely trust it should be what the alternator puts out plus a bit of head room.
Mine is 180A alternator so im guessing 240A may do the job.

maybe pass on the ioxus cap? it has an ominous disclaimer.....

just on that item, i don't understand how these online companies are selling these things to people, aaahh whatever.

"Disclaimer

This capacitor module was previously the subject of two NHTSA motor vehicle safety recalls for use in on-road vehicles due to the possibility of an internal short resulting in energy from the battery draining into the power board, further resulting in smoke and possibly fire.
