    • The perfect band-aid
Style: 1.0 Farad
I knew I needed one going into my subwoofer install. The car had stock subs with about a 80 watt amp. With the stock 8 ohm subs, the voltage was fine with the high amp alternator I put in years ago. I tried 2 ohm subs on the stock amp, just to see. It didn't burn out the old stock amp, so that was nice, but it really dragged the system voltage down to about 13, volume depending. I put in a 600 watt rms amp and sub combo with this capacitor and the voltage holds pretty steady at 14+ regardless of how much I want to damage my hearing. Perfect. And the resistor worked fine to charge up the cap. It probably took a couple minutes, but did what it was supposed to. The cap didn't appear to respond for several seconds, so have a little patience with it. ... show more

    • Awesome
Style: 1.0 Farad
Back in the day, these were expensive. Now, they are cheap. The fact it has an led voltage display is a bonus. Great deal for $35 bucks. I used it to compensate for the 8 guage wire i ran to 2 powered subs. (120w each rms). Might be everkill, but i like it. NOTE: be sure to use the included resiser to power this up the first time, slows the charge time. Takes awhile to charge. Also keep this resister if you have to remove it and discharge it. ... show more

    • So far, so good
Style: 1.0 Farad
So far, this capacitor is working well and solving my issue of radio shutting down due to voltage sag during a bass hit with my Alpine PLT-5 that is probably a real 200Wrms. The capacitor appeared to show up already charged as the pre-charge procedure didn't light the LED. So I connected it to the battery, there was a very small spark - the same as any time you reconnect the battery - and the capacitor lit and behaved normal. So far, I would re-buy this cap for a modest system and as long as this review is up, it's still working well. The fact that the unit shows up in the kind packaging that would be used in a store, where warranty is somewhat implied, would imply this is intended to be a legit product. ... show more

The Belva BB2D works great. But first, lets get the little stuff out of the way. The resister for first charge (and discharge if necessary) is incorrect in some way. The guy in the Q n A who used his test light nailed it. my resistor did not work and I used this idea and it worked like a champ. Basically put any type of resistance (like a light bulb) in series with the positive for the first charge (or across the + and - to discharge for safety) or if it has been discharged to work on system. Cap's store a lot of energy, these techniques are important. Discharging. (Decreasing voltage when stereo is turned off) A cap will naturally decay when no power is flowing. Decreasing voltage until the circuit board shuts it off at 9.5Vdc (I believe that's correct, but hey, no quotes) is normal. This way the cap is still 3/4 the way full when the system comes on. This is why you charge slowly with "resistor" (pronounced Light Bulb) the first time, the cap is empty. this stops the cap from over taxing your electrical system each time you start your car. Blue light. Cover it. Be creative. Why I am writing this review. I enjoy my music. I have been into car stereo for some time and have installed about a dozen systems. All under 1000W systems. About 5 years ago I built a 1600W system All JL Audio amps. This system included a 250A alternator upgrade and a 1/0 wiring kit. I have been experiencing "cut out" or "overload" mostly for the sub and sometimes the tweeters. Lots of troubleshooting and a little google searching led me to the idea my VOLTAGE was DROPPING. Naawww, not with my BIG ALTERNATOR! Surely not. Turns out, YEAH! Still feeling unsure about a cap purchase, I saw this Belva BB2D for only $40 bucks. Wired it in and VUAL LA. My system is Pa Poundin'. It Works! The techy stuff. Pioneer DEH 80 PRS head unit, JL Audio HD750/1, JL Audio HD 600/4, JL Audio 300/4v3, JL Audio 12W6v3-D4 subwoofer, Focal 165FX in front, Boston Acoustics SX60 in back. 600/4 feeds mid-woofers and 300/4 feeds tweeters. All crossover/ slopes/ levels/ eq are set up in the Pioneer head unit. I removed one of the the 3rd row seats in an suv and made a platform to mount my amps, covered it with a board and made a custom, sealed, 1.0cu ft sub box that fits over the "arm rest"/ rear wheel well. All 4 mids and the front tweeters are custom fit into stock locations. The rear tweeters are visible. Buy this and get rockin'! ... show more

It works great. Hold enough power that my 4000 watt sound system does nothing to my electrical system.

    • Bad Capacitor was sent out. Would not hold charge.
Style: 2.0 Farad
The item did not charge as specified by the directions. The readout flashed as if it was charging for over an hour when the directions state that it should only take 5-20 seconds for the light to dim and readout to stop flashing. In fact the light got brighter while flashing until hooked it up, then it stopped and the readout showed my vehicles voltage. Before hooking it up though, I put a voltmeter on it and seen that it was losing charge quickly. After about an hour of charging, I decided to remove the resistor and hook it up and then the readout showed my charging system from the car. That did work correctly. I used it for a day or 2 and it seemed to be doing fine and then I did some reading/ research and everything shows that capacitors should hold their charge indefinitely or until discharged. I did a test, I unplugged the unit from my charging system and waited 10 minutes. From a 12.5V charge in only 10 minutes it was down to 4V and falling. The unit is defective and I should not incur a restocking fee as I hope they do not plan to sell this again to someone else. I'm not saying they are a bad company or brand as sometimes there are bad electronics out there from major brands time again and that is to be expected. Just saying this was a bad unit so I have to give it a bad rating. 1* ... show more
