Belva BB1D 1.0 Farad Car Audio Power Capacitor with Red Digital Voltage Display

Works great. And as intended 10/10

Super easy to install. We'll built and looks great! Definitely helped my charging system keep voltage level. No more dimming lights!

I assume it does good. I have installed this in a 1987 F150 along with an 1100W amp. Headlights do not deminish under the heaviest of loads so far. This product would get 5 stars....two reasons why it doesn't for me. 1.) The instructions on how to charge it aren't clear. It comes with a separate small circuity board with LEDs, small capacitors, and two obvious slots (one positive and one negative) to install on the main capacitor...but for what reason I don't know. I did use it to charge but only used the positive side....not sure if this was correct. While charging the on board volt meter showed the voltage increasing however the moment I would disconnect the positive battery terminal after charging the voltage would begin to drop...and fast. I think it is still doing it's entended purpose, it was little frustrating during install. 2.) The second item is it has a bright blue flashing LED that comes on when it is under load (i.e. bass is hitting hard). At night this lights a lot of the cab up blue....distracting...I have had to place tape over it so shadow it...All in all it looks goods...comes with all the mounting hardware...and does what it is supposed to....and a great value....

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.

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.

This trash doesn’t pre-charge. I followed the instructions and watched a few YouTube video tutorials but still can’t get this junk to pre-charge. The solid blue light is on but the red digital meter is flash on 0.0 after leaving it connected over night. I started the first charge at around 5PM and by 7PM I got not charge. So I left it connected overnight and still no charge. If anyone knows how to get this garbage to work please fill me in. If I don’t get any answers in 2 days I’m sending this inferior crap back for a refund.

Gracias

Easy to wire, but the display stays on all the time and i still get dimming of the lights. But with that said, the system is more cleaner and bass is more crisp.
