Description

View largerWHAT IS A CAPACITOR?A capacitor is a passive (a component that consumes but does not produce energy) two terminal electrical component. In building a sound system for your car, you would want to use a capacitor for a couple of different reasons.WHY DO I NEED ONE?The main reason a capacitor is always recommend, is for power reserve. The capacitor stores energy and releases it very quickly to the amplifier(s). How does this help? It’s very simple: Music is dynamic, no matter what type you listen to. The dynamics in musical content can vary from soft voices, and very quickly transition to thundering bass notes. These moments are where the benefit of having a capacitor is heard. The amplifier requires a constant amount of steady power to function efficiently and power the speakers. A capacitor will keep the power going to the amplifier consistent and stabilized, which means a better sounding system. IMPORTANT: The remote output of the head unit is connected to the remote turn on of the capacitor. The capacitor will not function if the remote wire is not connected to your head unit.SPECIFICATIONS1) 3 Digit, Super Bright Red LED Voltage Meter 2) Capacitance (microfarads): 2,000,000 3) Working voltage: 20VDC 4) Surge Voltage: 20 Volt 5) ESR (equivalent series resistance): ˂0.00195 Ohm @ 120Hz, 25ºC 6) Capacitance tolerance: +/- 10% 7) Chrome Plated Posts 8) Dimensions: H 10-5/16” x D 3” Charging The Capacitor View largerCHARGING THE CAPACITORFirst make sure that all the connections according to the diagrams in the instruction manual are correct. Pick up the cable coming from the POSITIVE (+) battery terminal. Place the supplied charging resistor between the end of this cable and the positive terminal of the capacitor. The capacitor will begin charging. Charging generally takes 5 to 60 seconds. During charging, the voltage shown in the 3 digit display will rise rapidly, then slow as it approaches the voltage of your vehicle’s battery. When fully charged, the display voltage will stop rising. If you have a voltmeter, you can first measure the voltage of your car battery. Then you will know with accuracy that the capacitor is fully charged. CAUTION!! During charging, the resistor will become hot. This is normal, but exercise caution during the charging process. After charging is complete, remove the resistor from the incoming positive cable, and IMEDIATELY connect it to the positive terminal of the capacitor.View largerWiring View largerView largerView larger

Works for Amateur Radio also
Style: 2 Farad
I have a Ford F-150 with the 3.5l Ecoboost engine. This vehicle has the automatic stop/start "feature" that shuts the engine down at stops and restarts it when the foot is removed from the brake or if the battery needs charging or the AC needs to run for cooling or other reasons. It is supposed to save gasoline. It may do that, but it has some unfortunate side-effects. One of those is that my Icom IC-7100 can't take the voltage sag that happens when the engine starts. It will reboot. Ford did something with the built-in system so that continues to operate, so I knew a solution had to be available. This was the solution. I paired it with a Bridge Rectifier diode to ensure that the capacitor would be charged but not feed the power back to the battery when the engine starts. It provides the voltage stability that my radio needs. Now I don't have to remember to shut the auto stop/start off as the radio will happily continue to operate through those cycles. The capacitor will operate without the display. I did however connect a wire to the radio through the auxiliary connector's pin that has voltage when the radio is turned on. I use the same connection to power another device that is only active when the radio is turned on. The 2 Farad capacitor is likely way more than what was needed. However, it was available at a good price, being only a couple more dollars than the 1 Farad capacitor. It is rather large, but I have it located under the rear seat in the F-150 and it fits well there along with the other radio equipment. Bottom line is that I can recommend this for solving the radio reboot problem for those who have the same problem. ... show more

Works like a charm so far.
Style: 2 Farad
Installed last night. The instructions say nothing about connecting the remote wire during the charging process, but it does need it. Only took about 30 seconds or so for the capacitor to charge with that little diode it came with. Reached about 10.8V then stopped blinking. Status light never came on like the instructions state it would, but the decimal point was blinking. So far so good. First time it fired up, it showed 12.1V and nothing blew up. I`m happy. ... show more

Good so far!

It was cheap enough for the size. I'm running 2500 watt amp on a 2500 sub. It has not failed one time and it does the job. So for us it's just fine for now.

Works for me
Style: 2 Farad
It works for me. My headlights dont dim anymore when the bass drops. I'm using it on a digital Alpine 5 channel at 900 watts RMS. 4x100 for the speakers and 500 for the sub. The only downside is it's a 12volt and the amp is designed more for 14volts.

NO Good

I should haveinstalled it right away. Does not charge and voltage meter does not work. Too late to return.

You get what you pay for.
Style: 2 Farad
The packaging is a horrendous nightmare designed to discourage returns. Typo instruction book pic with reversed polarity. LED and digits way too bright. Supplied charging 51 ohm resistor is too high value. Used 8 ohm 20 watt resistor and it charged correctly. Otherwise ok. Voltmeter is accurate and useful. It was holding 11 volts when I unpacked it so its probably a capacitor. If youre a ham or electronics tech this is acceptable. If not, spend more and get a more coherent manual and parts kit. 3 stars cuz it was inexpensive. ... show more
