All About your RFC30F:

How to install a car audio capacitor:

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.
