I've been researching power options to supply my car with enough power to run 3500-5000 watt rms audio system. I am going to be running 2/0 awg gp ofhc wire. The big 4 upgrade and have a xs power d3400. So I am confused, about battery options. Option 1: Should I keep stock lead acid under hood and put xs power d3400 in trunk for audio and get a 250amp H/0 alternator. Option 2: an xs d3400 under hood, another one for audio in trunk and a 250amp h/0 alternator. So 2 xs power d3400 batterys for this one. OPTION 3: this one is the most confusing one but thinking of options of being able to put in different vehicles and cost effective. Keep the d3400 under hood and add a lithium 15ah-25ah battery. Been doing research. With this setup I could keep stock alternator to my understanding. Now issues with lithium is who to go with and compatibility for a car application. Lithium currently has it's limits such as to much cold or heat as well as charging to fast. I know limitless would work and the other well known brands but they are just to much. My biggest concern is who to go with and keeping the lithium safety that limitless batteries have and staying within a 400$ dollar limit. This option would be to ensure I wouldn't need a h/0 alternator.
Hoping someone has these answers.
