First, this product really works as described. I have a 1000 watt Planet Audio amp that is a voltage and amperage hog. I could actually see my light dim when running the sound moderately. I was sceptical that this simple cap could supply enough capacity to effectively solve this dimming issue. After about 3 days, the cap was operating to perfection. No more dimming lights. Also, I notice my speakers actually sounded more crisp and edgy. I wonderful improvement in sound quality. I am very satisfied.

Works fine, only weird thing is that the voltage display does not have a remote wire hook up so it stays on after you shut the system down. It eventually turns off, I don't know how, but it doesn't drain the battery or anything. Looks clean, great for the price, would recommend.

Was looking for a capacitor to help with my car's battery and alternator with the addition of a rockford fosgate preloaded 12" sub, box, amp combination. Capacitors are essentially the same despite the brand. This one features quick negative, positive hook up. No rem wire to turn it on. Con - when it displayed 13.8 volts on the cap, the voltage going to it was actually 14.4 volts on the craftsman voltage meter. Otherwise, nice product.

I installed this to help with headlight dimming at night and it helped a lot. I have a Pioneer digital 800 watt RMS amp and adding this seemed to help make my amp come alive. Installing and charging was stupid easy. My subs are hitting harder and seem to have a better sound. It didn't totally take away the headlight dimming but it's not nearly as noticeable and it only does it slightly on certain hard-hitting songs. My alternator is 165amp and I have a stock battery so I'll probably upgrade the battery in the future too but I don't go around "bassing" all of the time either.

Before I was running just a Boss 1200 watt woofer with a Boss 1500 watt amp and I could definitely see dimming. I upgraded to a 15'' Earthquake sub and knew I would need this. I see no dimming at all now, works perfectly.

WILTON, CA
April 7, 2015
So I was looking around for a good cap to buy to add onto my system. Honestly I didn't find any I liked that weren't super expensive like $70+. My friend actually recommended this cap to me since he's had it in his car for awhile now. So I thought well for $25 why not give it a shot. Keep in mind I'm running a single 15" Kicker CompD in my trunk so I'm pulling 1200w RMS and 1500w peak. The cap does good and does what it's supposed to do. But for the amount of pull and wattage my sub needs, the cap can't keep up so after about 3 mins or so of listening to music at a high volume, you'll notice the bass quiet down and/or my headlights will ever so slightly start to dim with the beat. So I wouldn't suggest this cap if your system has a rms of over 1000. Other than that the cap is great. Looks cool. Has a blue LED that blinks when there's any sort of draw from the cap. DO NOT OVERTIGHTEN the terminal bolts. They will strip out. Only a little tightening is all they need to hold them. For $25 though you can't go wrong. It definitely helped my system even if it can't keep up all the time but I'm not thumping for hrs either. Everyday driving it helps keep my amp stable for regular listening.

Definitely recommend the product if you have a starter sound system set up. I have a 12" Kicker L5 with a pioneer champion series 500 w rms in my 99 v6 mustang, and noticed that it would hit real hard for a little, then the power would noticeably fade. With the capacitor the power is constant and you are always in control of when you want to slap. It looks awesome, my friends always confuse it for NOS. If you are a beginner however, I recommend going to youtube to learn how to connect it and charge it. It is very easy, and I did it myself.

I have been running this capacitor for a month and no complaints thus far. This is my first capacitor. Normally I do not use them, but this is a brand new car and I wanted to protect the battery. Technically, I only needed a 1/2 farad cap. So, I'm sure it is being under-utilizing. I like the led volt gauge on it.

This is a good cap and works as stated. For those looking at the 3+ farads just to educate you if you get three of these versus a triple farad you'll get more out of three of these wired in parralel and faster response for your subs.

This is the best investment I have ever made. And it is so cheap! Single sub and amp used to make all my lights, inside and out dim like crazy. I was skeptical about this, because I have never ran a capacitor before and have heard different opinions, but man this thing is great! None of my lights dim at all anymore. Absolutely fantastic, if you're questioning this purchase, don't, just get one!

This 1 farad capcitor does what it's supposed to. I'm pushing more than the recomended wattage for this particular unit. It is helping the dimming situation. But for my particular situation. I needed a bigger CAP. It includes a small charge piece to pre charge it so you don't get a spark when hook up the power. I couldn't get it to pre charge so hook it up. For a spark and it was good to go. Probably not the way to do it but that's how I did it

I was skeptic about buying a capacitor because so many people say they're pointless. But i was having problems with headlight dimming. So I went with a cheaper one. After connecting it, I immediately noticed the kick drum was hitting harder. Not a huge difference, but enough that i was glad I bought it. Also, it greatly reduced the headlight dimming. At this price, I would recommend to anybody that has an amp less than 1K watt, having headlight or other electrical issues.

The Belva BB1D is a well made, solid product. The one complaint I had was with the mounting brackets; the rear bracket had a lip on it that I had to remove with a dremel to fit it in my truck. Capacitor itself is perfectly fine with being under the hood, near the edge of the hood. Install was very easy, just plug and play. Initial charging of the capacitor only took a few seconds and it works flawlessly. Very happy with this product.

It's actual capacitance is probably not anywhere close to 2 farad but eh, it looks good and works as a distro block. Be wary of the allen bolts on top, they are nowhere near 5/16 so a normal ring terminal will be sloppy fitting on top.

Capacitor seems to work but there is a blue light on the top where it reads voltage. Every time it is charging the light blinks off and on. It's kind of annoying because any power being used at all it starts to blink. Example rolling up-down window applying brake peddle or anything makes this charging light blink.

This is a good cap. The issues I had was the resistor did not light up when charging. To charge this cap, put the resiston up for 10 seconds or so. Once charged, when you go to finish the install the cap should be in the 12 volt range. I bought this to replace a 500k scosche cap. That cap ways way too small and point less being that I have a 2000 watt belva monoblock. This amp work really nice. It goes great with the belve amp. For 40 bucks, you will not be unpleased with the purchase.
