Just watched a bunch of videos on this and this was the best most simple and easy to understand. Great job 👍🏽

[@Markav1ch]

Selling my sedan and keeping my sub/amp/cap. So glad that not only did I keep the included resistor but I also recently found it while tidying up a drawer. Thank you!

[@christopherbodden506]

Thanks for this ive seen many saying the resistor doesnt work i knew they were just doing it wrong its been 20 years since i put a cap in lol

[@nickmaiorana5057]

Thank you for that helpful video.

[@timmalinowski62]

Very helpful. Thank you.

[@josedominguez161]

Thanks bro that was very very helpful

[@HiFiVector]

Thank you!

[@tomduerr988]

Best video I found. I hooked mine up without doing this today. Never knew about this. Only had it on for a minute. Will it be okay?

[@hoebangin1]

I hooked a new cap today and it started stinking bad , and got super hot. was a $100+ guy said he charged it. sounds like he didn't from the video?

[@leonardkellum6984]

so when its been sitting without a car battery I need to install a flashlite bulb between the fuse parts going to the cap, which is easily accessible, until the bulb goes dim.

[@joeJoe-pb3su]

Is there a brand you recommend for a 1000 or 1500 watt system. ? I saw a guy get like 6 caps for his sytem and it help it got louder and didnt kill his battery. 😊

[@kirkphipps745]

What resistance in the resistor

[@endyX286]

how much value resistor that i need to recharge the caps?

[@quevicular]

what ohm capacitor and does it matter for the amount of FARADS that the capacitor has?

[@johnny-sr4fk]

Thanks brother

[@user-tx1no7oi1r]

What about capacitors without digital cap

[@thomastommy9864]

How do people usually deal with capacitor when you're doing routine battery maintenance, or perhaps you're replacing your aging 12v battery? Would people typically not have it disconnected long enough to drain it, so when you attach the battery again, you wouldn't see a massive spark? Or do people keep a charging board near the cap and always charge it when messing with the battery?

[@HiFiVector]

Disconnect and discharge the capacitor before you remove the cars battery.

[@clayscott8363]

I've always done it with a test light instead of a resistor

[@kevinlandis382]

I have a 2.0 audiopipe capacitor and I lost my resistor.. how do I find out witch one I need

[@HiFiVector]

We have them on the hifi vector website

[@TerrorSquadGraphics]

So I got a skar 1200 mono running two 12 skar sdr series what cap u recommend

[@HiFiVector]

I don’t recommend cap you be better off getting a second car battery and just sticking in the trunk even if it’s a Cheap small one is better than a cap

[@pepe7048]

Hey, I had a question for you. Do you know how to charge a rockville rfc30 farad Hi buy it brand new I try to figure out how to charge first time

[@HiFiVector]

Not 100 percent on that model but should be similar to how I mentioned in video.

[@choosyonee]

What if I was just starting to charge the cap and had to disconnect and not finish charging it, can I just jump back in and recharge it? Or do I have to do something else? Or did I damage it?

[@HiFiVector]

You’re supposed to discharge it completely when it’s disconnected from power. Then start over with the charging process. The cap will only hold power for like a minute when disconnected but they need to be either discharged or connected to power. They can be damaged by not being one or the other.

[@choosyonee]

@@HiFiVector ah ok yea I did not discharge it or had it connected to power, had to cut the process shortly after connecting power to the resistor so I guess I will have to buy a new one

[@keithmiles3045]

I have a rockville 50 fared cap. What size resistor should i use

[@bennettgetshall9969]

I've got the Stinger 50 farad cap and I just used to test light and it worked fine

[@bennettgetshall9969]

Like this dude said you just need a buffer to kind of slow down the voltage so it can charge evenly and slowly

[@marshallfischer8686]

If reusing an old cap do you need to do the recharge step?

[@HiFiVector]

Yes

[@marshallfischer8686]

@@HiFiVector thank you

[@aundraymitchell609]

Will any value resistor work?

[@HiFiVector]

No it must be a certain kind.

[@marcellusrumhp]

How often do you have to charge a cap

[@HiFiVector]

Only when you initially connect it to power. As long as it is connected to power it’s good.

[@byazzie3927]

So is it safe to not discharge the capacitor through out the day? Or do I have to discharge the capacitor everytime I go into a store? Please respond lol new to this

[@HiFiVector]

No, you don’t ever have to discharge the capacitor unless you remove it from the vehicle or remove power from it. For instance, if you’re replacing your car battery and you need to remove the car battery. Then you would want to discharge the resistor and remove it from power before you remove your car battery, so basically you only need to manually charge and discharge it when first applying power to it and then when removing Power from it

[@byazzie3927]

@@HiFiVector thank you so much! I appreciate it.

[@scottborst5430]

Quick question can you use more than one capacitor in line?

[@HiFiVector]

Yes

[@scottborst5430]

@@HiFiVector Thank you very much

[@scottborst5430]

Would you have a video on how to connect more than one capacitor or an battery together?

[@HiFiVector]

I don’t sorry.

[@joeyortiz13]

I don't know how many of these I've seen so far but what is the power supply where is the power coming from to charge the capacitor nobody has said where the power is coming from

[@HiFiVector]

The car battery and alternator is the power supply.

[@tonyswagz]

I bought this today but now i feel like i made a mistake because i only use my vehicle for recreational purposes on a weekend so I don’t think this will work for me

[@HiFiVector]

As long as your battery doesn’t go dead and you drive your car every week or two it’ll be fine. The only problem using a capacitor is if you let your battery go completely dead.

[@tonyswagz]

Thanks for the reply, I usually disconnect the negative terminal of the battery while the vehicle is not in use to prevent it from dying quickly over time…. But that wouldn’t be good for the capacitor too right?

[@HiFiVector]

Correct that would not be good but you can also buy an expensive battery maintainer and put on your vehicle that will actually help your battery in the long run and prevent that from happening here is a link for a great one I use if you’re interested. amzn.to/3XBsCBy

[@tonyswagz]

Thanks so much man I appreciate this and its on Black Friday sale i will definitely buy one now and I’ve subbed to the channel im about to install my own system soon and your reviews are great

[@HiFiVector]

You’re very welcome thanks so much for subscribing!

[@doltin420ify]

Can't you just use a 12v light bulb

[@AF-ib7ts]

The capacitor stays on when the vehicle is off. Is that Normal?

[@HiFiVector]

Yes it’s normal unless yours has a remote key on terminal. Some do some don’t.

[@AF-ib7ts]

@@HiFiVector thanks, it has an LED display showing voltage. I was worried that it may drain my battery

[@txddyfarquh3916]

Q. 1: do capacitors come in higher farads and would using a higher farad cap be better for car audio? Q. 2: Can you use a 2nd battery WITH the capacitor in your audio setup?

[@HiFiVector]

Yes caps come in a wide range of farads ratings. Yes you can use a CAP with single or multiple battery systems.

[@SheikhN-bible-syndrome]

Super caps are 3000f at 2.7v so 6 would make a 500f bank but even at 500f that's not much power
