I need some help with my new build. This is the most power I'll have ever ran, and I'm not exactly sure what all I need.
My amps are an Audiosystem X-Ion 160.4 = 640w
And a Taramps DSP3k = around 3kw. So I have roughly 3640w being drawn, but I only do music so should be a little lower I guess...
For the alternator, I'm looking at this Mechman 270a alt G Series 270 amp 6 phase Nissan / Infinity 3.5L alternator - Mechman Alternators
How many batteries do I need?
As of now I have a used Deka Intimadator 105ah (not installed) and my regular, almost brand new wet cell (installed).
Do I really need to buy two large batteries of the same type and age and a smaller agm for the front? Or would I be ok to use the deka with another battery of similar size, and isolate* it from the wet cell up front (*which idk how to do yet).
If I end up getting three new batts(2 in back, 1 smaller up front, all agm) do I need or want to isolate the smaller one? That way I can have two for the amps and the small one for normal car electrical?
I'd also like to know exactly where all I need fuses and how many runs of + & -
I have a Knukonceptz fused distro with 3 fuse holders as well as one Knu inline fuse that has a 250A rn from previous build, I'm assuming I'll need a 300A now for the taramps 3k, right? The audiosystems amp has 3 x 40a on board fuses already.
Do I need to run negative to negative on the batteries or just have multiple grounds?
Thank you.
