Im looking for a 20-40farad cap that has:
(1) 0 guage
(2) 4 guage
It needs those for each positive and negative.
I have yet to find one that actually has 0 guage inputs.

Why do you think you want (or even need) a cap at all?

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Well im not so sure if i need one anymore. But i will have a 140 amp alternator. 2 red tops and a JL 1000/1 and a 400 watt speaker amp. I had a cap before with my crap system that was about the same wattage. I just see the cap as a way to smooth out the drain on the batteies.

That's a common misconception. If your electrical system is already up to the task, a cap is completely unnecessary...

Yup, what good is a CrAP these days is really beyond me. Granted they do make a fancy distribution block though. Lightning Audio makes a cap distribution block that fits this bill. The LL10D or something like that.

Here's a link that talks about automotive electrical systems.. including caps. https://www.betteraudio.com/geolemon/newmain/battcapalt/ I agree with the graphs.. caps can help, but I don't know if it's noticeable to the listener. In any case, they don't hurt, and can be used as a handy dist. block. Jim
