Down4sound SuperCap Banks 

u should put it in a case that looks like a battery so there is no worries about movements and shorts, make it more sturdy

Honestly Jonathan, D4Sound is really cutting the edge with these Products.. just Remarkable..

I love the fact it's open lookin like a zip tied car audio d4s energy drink 6 pack bro..... fire

Glad to see you're doing so well JP!. Dedicated s.o.b. From lawns to entrepreneur! Good shit man!! I wish you luck on your journey!

Freaking LOVE my Xs Power 500 Farad Supercap. Stabilizes the shit out my electrical system. Huge difference in dynamic range. Way harder kick drums and other fast bass notes, and it takes a lot of the load off of my electrical system. Wish I'd have done this 30 years ago.... Wait, you couldn't buy these 30 years ago ;)

Everyone is an adult until someone shows up with bubble wrap. 🤣

Will you please show us this already set-up (mock or real install) demonstrating exactly how to install as if were installing into vehicle that has one AGM under the hood? (e.g. XS Power D3400) Start to finish from the charging, to testing, to installing, to enjoying.

I bought one of these from you, but curious is it ok to hook it up to an AGM battery? Currently that’s how I have it with no problems but I’m not sure if the constant discharge on the super cap will cause the agm to die faster.

Next purchase sweet

Do you need to make a video on how to install it to make it more easier

Idk why ppl complaining about the zip ties and not coming with a housing. Y'all must not know the average price of a cap bank like this. And it's welded together Just got the 200 amp alternator.... Def gonna SAVE UP and get this bada$$ Cap bank

Question. I have 4 lto 6.0 batteries… But my system is only a 15k watt rms system … I have a big 3 with dual 0 guage to the underhood , another dual 0 guage to my 4 lto’s in the back … How many supercaps should I get

Is there a big difference between agm and lithium?

Can u come from the front battery to the super cap bank, than out to the amp? How many watts can the bank take?

Put that beautiful thing in a housing its $350

Nice capacitor bank

Bought one today .

Can i put just the battery in my trunk and use that till i get the super bank ? Basiclly want to install in stages.

Just purchased D4S Lithium battery! U like to know would I need the supercap bank Also or can I just run the power from under the hood to the lithium to my amps

besides lithium what would you recommend to run a soundigital evox 12k 2ohm and a sundown sfb 200x4 amp on with a Ohio generator 350 alternator with 1/0 ofc wire?

I have 3 brallie batteries on my harley running a soundigital 5000.1, in pushing two dvc sundown 10 midbass speakers in my tune ported bags, i would like to keep my voltage at 13.8 to 14 volts. What cap set up would you recommend?

Ever wondered how to charge a cap bank? check this out! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ev6TywVbnUQ.html

I'm installing a capacitor bank in the trunk for my audio system. I already installed a cut off switch. Do I need any other fuses besides the one next to the battery?

Could I add just one cell to my car audio system? Or do i need all 6?

So after charging the banks with a portable charger will the alternator charging from there

Who runs dedicated power and ground runs directly from alternators to rear batteries?

Will this product stop voltage spikes when bass hits

Those are so dope jp!!

Pawer Bank 12 volt? Portatil?

You can't even put a case around it ?? Zip ties are a bit tacky bro ! A case would be much safer and massively better looking ! Love your vids !

Would any of the d4s xs power battery cases/or d4s hold downs fit that super cap bank???

Awesome.

Does that wrk wit the d4s 6i COPPER- CERTIFIED BASSHEAD BATTERY DISTRO BLOCK - 6 SPOT FLAT (PAIR)

I’m curious if these are maxwell supercaps or yinglong caps. Regardless they are both top notch

So I see Capacitors are coming back in again huh JP??? Looks nice though...

Hey jp can I ask you a question I have 2 orion 17k how much banks of supercapacitor in need to run does ?

Sweet,, I got to get me one 😁

Can you mix with lead acid battery’s?

U the man JP.

I was wondering i don't kno to much about this new equipment but can u use more than one of those batteries like have 3 or 4 batteries together im shr u can but I'd rather be safe than sorry u kno if any1 can help me out and let me kno i appreciate thanks great video [☣✌💪🔈✌💪🔉✌💪🔊☣]

The zip ties are cheesy. It's not a good look.

Have questions about supercaps?? Be sure to watch this video! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oncw9nKc_gg.html

I ordered one 2 weeks ago it came this week with no hardware, sent 2 emails and 2 contact questions thru the website still no response, so jist wondering why you sat it comes with hardware and I didn't get anything but a lollipop and sticker, I also ordered 2 zv5 15s 4 months ago and one had a torn gasket which they did replace but im not saying that I'm mad but I am definitely getting frustrated not getting a response so I can get the hardware so I can use this, I payed 350 and I tried home depot but can't seem to find the right size screws and I don't have the little bulb to use to charge it so I basically paid for a six pack of useless caps

When you change only the stiker but still the same thing.(China)

POPPIN BUBBLE WRAP FTW!!!

Nice 👌 JP

Can you hook that up inline from your starting battery if your not using a supplemental battery?

Bro ... we need to show us your new bomb system im waiting for this like apocalypse day 👌👈🤙

And for the longest time the 1 farad cap was an old military surplus cap that nobody knew how old they were....lol...and they added the volt meter so people thought it was doing something...it was nasty scam back when caps first came out

Nice!!!

Bad Ass hope to get 1 soon

I got the same one several years ago for my Son’s system. Cut that thing open!!!

Some say caps are snake oil. They say just use a Li battery, big3 and h.o. alternator. Some say 1Farad is enough capacitance for 2000watts. I disagree with both statements.

What is your merch??

Hey jp, i was always told you cant mix lithium and agm..so if i have an agm under the hood, then i cant run your lithium and cap bank..is this correct

What about a bms? Thank you

Any Ballance Boards Included?

How do I charge it up and hook it up

Damn I want to buy that sexy Cap Bank sooooooo BADDDDDD ...... 😍

I need this. and have recently threw away $150 for 2 'four farad caps'. Volt meters. 275 anmp alternator over 3k in led acid CCA's, and headlights still dim. 0gaOFC wire. I Need This. and will have one of these soon.

It would be cool if you wrapped them like a six back of beer or pop .

Make a casing for it and I'll buy! Need one bad

Yes the title told me,lol

It looks kind of Chauncey for what you're asking for it and needs to be in a case. Not that it isn't useful and that it don't work I'm sure it does. But it would look a lot nicer if it was presented better.

Answer the phone!...lol Hey do you fuse the Cap?

It will take u around 500 of thoses single caps to get what u offer in one . Love it

Just ab ADD for Down 4 Sound!!!!!!

Your small lto lithium battery shipped to canada is like $850 why are there none at canadian dealers

Do these come with the light resistor to charge it?

Im.goona pop some Caps.

And what is that for???? To have more power?? To have better sound????

Zip ties?

Yoo whats up man

Might order one soon all these people complaining about a case make one or buy a roll of electrical tape

👀👀👀

👍👍👍🇹🇹🇹🇹🇹🇹...

Hello you sell amp for subwoof

WHAT!!!

JP!

I bet so many people just hook these right up without charging them the right way. That is not good

FILLED WITH SAND WHAT?

I feel like jp isn't being forthright with a few aspects here, partly because I don't think he really understands capacitors. There's a reason why they have liquids and sand in capacitors. They use dielectric materials, electrolytic materials, and of course conductors and insulators.
