1 farad caps serve no purpose for car audio (well I can think of one application, but that’s very specialist and for db drag only)

either buy a super cap bank or get an extra battery (headway lithium can go in parallel with the stock battery) 👍🏼

 

I have both of those as well
(actually thanks to your recommendation previously)
i would be using the 1 Farad caps as noise filters, to keep my power lines extra quite.

 

Battery’s and super caps do that anyway… you don’t need 1f caps

 

yes totally 100% agree. i do think larger super caps & batteries will add filtering. i'm just trying to be extra prepared for noisy system so i can add additional components.
i'm also learning/enjoying testing out the caps. i'll post some test results later today hopefully. it was pretty fun, learned some things.

now i have seen some videos, although i cannot find them now..... , may have been taken down, showing the 1.0 Farad caps helping reduce noise in vehicle on the power lines.
these were some oooold youtube videos. i've also read some anecdotal stories of them working for that. and some guys like them for that.
i think amplifier power supplies should have filtering on their inputs to help with this anyway..... but from the stories i have ready & my experiences, sometimes there's still noise.

 

here's a few pics of my test setup and the results of the cap one I tested.
still curious if anyone knows of any caps that are actually 1.0 Farad?

edit: need to upload pics later on.

 

Perhaps you have a reason for wanting exactly 1.0F, but if not, these are pretty economical...

I just picked up a Brax 1.0 farad cap to test since they’re a reputable company and it will be a solid comparison to the μ-Dimension model I have which uses a bank of 92 ELNA capacitors instead of a single large one.

Here’s a photo:

 

^^ cool. let me know how your testing goes. so when i tested/measured mine, i removed the display & circuit board that came with it. the board on the unit i had, had some "funky" behavior, i'll just call it that. it also drained the cap super quick.

 

 

 

Nice, I'll be using a Siglent SDS1104X-E to test mine and will post results.

 

dude, same exact scope.
looking forward to seeing what the Brax cap is made of.
this cap feels only ~half full of material
other than that is feels nice/looks decent. ehh well, it's a shame.

 

Brax caps are one of the best.

 

waiting on @Catalyx to test his
do they still make the 1F+ caps (price/place to purchase)?

ended up buyng a couple more caps to test out, i'm returning that Belva cap.

also for my personal use i would want to remove the PCB/digital voltage display, no need for those bits, for me.

 

hey guys, purchased some more car audio electrolytic caps and tested them out,.... Pyle "5.0F", Sound Storm "3.5F", & NVX 1.0F.
The Pyle & Sound Storm caps were 0.5F & 0.3F, very similar to the Belva cap tested above, except these were huge physically.
So pretty much the worst combination....larger in size/take more space and small cap value.

The NVX cap though.... tested to be 1.3F. Tested three different methods. I can post results below.
The NVX cap also comes with built in mini-distribution block, not bad.

 

some pics of the caps. the Pyle and SSL caps were larger physically.
