Description

Have you noticed your headlights dimming to the beat when you hit those heavy bass notes on your car’s custom sound system? Cranking up the volume on your system can put inordinate amounts of stress on your vehicle’s electrical system. Most cars today cannot handle the high power demands of custom sound system components hence the need for a dependable and powerful capacitor. Enter the Rockville RFC30F Digital Hybrid Capacitor. This professional grade capacitor is built to handle even the most power hungry amplifiers delivering a surge of up to 20 volts of power when needed. Rockville engineers have gone out of their way to design and put in your hands a high end capacitor at half the cost of our competitors similarly spec’d models. The RFC30F features a 3-digit super bright digital LED read out which displays the unit’s exact operating voltage to the decimal point. It comes equipped with heavy duty bolt down style platinum plated terminals which ensure a safe and solid connection. The built in IC Controlled circuitry alerts you if your voltage is too high (+17.5v) or too low (-10v). An automatic sleep feature helps the capacitor reserve power during lulls in volume levels, delivering it only as needed. With its sleek lines, modern styling and cool blue LED accents, the RFC30F will enhance the look of any sound system. The reasonably priced RFC30F comes with a 90-day money back guarantee. With its high quality build and superb performance, its a definite step up and a must have for your car’s sound system.

  • One powerful cap.
I have two sundown SAZ 1500D amps linked together pushing a pair of U series 12s and a rockford fosgate punch P600x4 on mids and highs and it dosnt even phase this thing. The volts never go's below 13, good guality cap.

  • Works good
I like that its not that big and it's not round. I tried others that didn't last. I'm hopeful on this one so far. It's tak3n care of the dimming lights and computer faults.

  • Great stuff
Great cap I do all my shopping at Amazon, I had ordered a blaupunkt 5000D mono amp and the installer said he wouldn't install it they had filed bankruptcy in 2006 they use to be good product 26 years ago and now are junk the company who took over our putting out junk so Amazon will take it back and I ordered a CT-sounds 1400.1D amp and was 200.00 more dollars and I guess the old saying is true that you get what you paid for.. ... show more

  • No more dimming lights
Very good product. Running about 1000 RMS and lights were starting to dim. Make sure you put the cap as close to your amp as you can. Would recommend to a friend

  • Perfect piece
Once I got this thing charged it helped tremendously my bass notes don't fall off and now my bass is so much more powerful and it does help on your electrical parts of your car overall definitely a good product now I've only had it for a day or two but so far so good and everything else that I've bought from Rockville has all been exceptionally well made and performed better than most kicker and Rockford stuff I've had for like a quarter of the price so if anything changes I'll update this but so far if it's like any of the rest of my Rockville stuff I don't think there's going to be any issues. ... show more

  • Lights still dimming.
I’m running a 3,000 watt amp and still getting light dim.

  • Powerful
I had this hooked up to two competition 12s putting out well over 1000 watts rms. This thing didn't let the voltage drop below 12v at all until it was max volume but it was still going above 11.5 volts easy. Best capacitor I've had in a long time. Hooked up two amps to it just to push the extremes on it. It never went below 11 volts at max volume. Money well spent. ... show more

  • It does nothing, except flash annoying lights!
It says 40 Farads, which is an insane amount of capacitance, but with 2000 watts of amplifier power, my lights (dash and headlights) dim when the heavy bass hits. Also, when I run it with the floor cover removed from my amp stash, the flashing blue LEDS light up my car at night, which I do not appreciate at all. So all it does is annoy me, and probably drain more energy through the flashing blue cop LEDs. What a wasted of time, money, and precious audio equipment space! ... show more
