I m needing help on the cheapest and most effective way to push 4k rms .i have a stock 120 amp alternator .had a xs power 6500d battery but it recently went bad on me .does anyone have any rocomendations on what i should get.i was told two d4s lithium 6.0s with a stock alterntor would power it.im trying to go as cheap as possible and would rather not get a new alternator as im planning on buying a new vehicle soon.

Any idea what your stock alternator charges at? People here recommend against the d4s lto6.0's.

Those batteries are hot garbage. The $800 you were going to spend on them you could build a 40AH bank of Yinlong or a Headway super beast with money left over.

I think you are going to need an HO alt of approx 300amp and a couple good sized AGMs in my opinion

Go easy on that amp with what you have so you dont cook it with the supply you have.

You might want to get a volt meter to keep an eye on it. You can find them cheaply on Ebay and several Audio sites and pretty easy to install

You may be able to locate a Local Alt place that will will build what you need/want. I have one I had built (a255) that a local did for me and still going strong a little over 5 years now
