GREAT! CAP

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.

ROCKFORD FOSGATE RFC1

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.

Awesome Cap

This Rockford Fosgate Capacitor I added to my system removed the headlight dimming issue. I love Rockford Fosgate.

Great buy!

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.

Badd Azz Cap

This cap works great, will keep your system loud and clear. Would recommend for everyone with a cranking stereo.

Even for your Welding Applications....

Operating to 18 VDC, providing a 600 watt-second spot welder with reliable zapping power.

Rockford Fosgate RFC1

Worked great. Used in my boat this summer and had no problems.

An absolute necessity

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.

Great RFC1 Capacitor, Great price and product

I had owned my last one for 6 years still worked when i sold my truck it was in!

Great Value!

Helped me with dimming lights problem on my Impala 2004.

Outstanding

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!

Good Capacitor......

Good cap, good price. Bought just in case.
Matches my other components. Good for one amplifier, or a system up to 1000w.
I like the look and function. The only thing that would make me like it more would be, if it had inputs for wire, instead of the screws for wire terminals, and if it had metal mounts instead of plastic. But, I'm just being picky. For the price, it is well worth it.

Love the new capacitor

This has really helped out with keeping the amp voltage and saving the battery voltage.
