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.
No
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.

ROCKFORD FOSGATE RFC1

June 6, 2011

Great choice, since I added the Capacitor not only are my lights much brighter, they don't blink and it save my battery and also my alternator, before I adding the capacitor I went thru 1 battery and a alternator. My system now has harder hitting Bass and higher Highs because of the constant power the capacitor gives. I Recommend this capacitor for those who especially have multiple amps.

I would highly recommend this product. it solved my problem 100% and then some (when cranked up my whole trucks power system would surge really bad from the alternator trying to keep up with the power demand). east to install if you are familiar with audio systems. products like this is the reason I have always been faithful to Rockford fosgate. great price by the way!

GREAT! CAP

March 8, 2011

I tried this product for simple fact that I just needed a little help under heavy current loads. This CAP does exactly that, It gives you that extra boost of current when you need it.

However, I do not recommend this product if you are using a DC/DC step-down converter as your voltage source. The CAP could possibly damage the converter.

I use this on two 100Watt subs, and it made a big difference. Definitely recommend this to anyone with a sub in the back of their car.

An absolute necessity

October 28, 2010

I've gone years without one in my system, just never really justifying the cost. Now that I finally jumped into buying one, I'll never have a system without one again. Sound is so much smoother, more precise hits, and never seems to fade. I definitely recommend if you don't have one.
Only problem is the instructions are real unclear for charging it. You have to charge it before hooking it up. Ask someone who has done it before if your unclear of what to do. It's easy.
