Capacitor Specifications

Capacitance (farads)
Capacitors are rated in farads, and at times microfarads or millionths of a farad. The more farads the capacitor is rated at, the more electrical charge (and wattage) the capacitor will hold. Capacitance is defined as the property of storing an electrical charge between two separate conductors.
1 farads
LCD Meter Display
Displays the current voltage and/or other specification on an LCD readout.
Yes
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
Any Gauge with use of Ring Terminal AWG
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.
Any Gauge with use of Ring Terminal AWG
Built-In Distribution Block
A built-in distribution block simply means that the item includes a distribution block. The built-in distribution block will split the single power input into a multiple power output.

Just enough!

September 13, 2014

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.

Nice product

April 13, 2014

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.

Much Better

June 22, 2014

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.

Works good for 1000w and lower systems. Excellent capacitor.

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.

Best investment ever made.

November 14, 2015

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!

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.

Seems to work

February 16, 2016

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.

I installed the capacitor. But when the bass hits hard the blue light blinks. Is this normal? I have a 900w Pioneer amp. My friend has the exact same capacitor and the light doesn't blink but his amp is smaller too. I checked all the connections and everything is fine. Is it normal for the light to blink?
A shopper on Mar 11, 2015
Best Answer: Well the only time I see the blue light blink is when I haven't driven my car for a few days and the voltage drops to I believe under 10volts? Not sure the exact voltage it actually blinks. Anyways, when the car is running no matter how hard my system hits the voltage on the CAP never drops below 12v. It fluctuates from any 12v to around 14.4v.
I'm running the Boss CE2505 5-ch amp rated at 2500W but, my setup is 150W x 4 and 250W on a single 10" custom subwoofer.
If you haven't properly charged the capacitor during the first install could be your problem. I'd suggest discharging the capacitor properly then re-charge it following the proper procedure. If that doesn't help then your system needs a more powerful CAP. Hope this helps.

Can I use the same ground mount for the cap wire and amp wire?
A shopper on Oct 6, 2015
Best Answer: Yes Ive done it but for improvement try using a ground splitter i forgot what its called but you connect both your grounds to it so there would only be one lead coming out and try making that one lead thicker like me im using 1/0 gauge on amp and cap and the grounded wire is a 0gauge

Best Answer: Yes you should be as long as the ring terminals for both the 8 gauge and the 4 gauge fit snuggly on the cap. My setup is 4g to and from the cap but I don't think it would matter with your setup.
