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.
20 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.
4 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.
4 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.
No

headlights dont dim

July 22, 2012

I don't have any other products to compare it to yet. This may be the reason that my amp cuts out at extreme volume output, others are that I may need a better ground, an additional sub crossover, or I may have a defective sub or amp. Overall I think this product is good. I think if I do another install I will upgrade to the next size up from this company and go ahead and throw the extra battery in the trunk. I seriously doubt this thing can hold 20 farads, (20,000 watts) of juice. However, it is still pretty heavy duty for a car audio cap. People with superior amps and subs dont touch what my system does, and I think its the cap rather than the dynamat or brand selections. Most people dont use a cap, and since they are less than a hundred bucks this makes them idiots. I may be an idiot for not doing a diode assisted installation charge, I'd reasearch the need If I were you. System still works well, I have a few kinks to get out, but I doubt the cap is one of them.

great product

March 1, 2012

Great product. Lights up cool, but the lights didn't dim at all. I was pushing 2 Kicker CVR's at 1 ohm on a DB Drive 1000.1 amp.

This is good stuff, but its not the best quality, I am living in Ukraine, and my father is electrician, and he says that this capacitor does not have 20 farad, only 2-3. but it very good looking in my car.
