## 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 RFC50F 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 specs models. The RFC50F features a 3-digit super bright digital LED read out which displays the units exact operating voltage to the decimal point.

Review: Works very good - Nice item
Review: Works Great!! - I really like this product, I bought 2 15inch Kicker L7 so I needed something that could help with the power plus with the 8k Amp. I like the blue color that lights up on it an the fact that it makes a "beep" sound when you turn the car on so it let's you know everything is good to go!! Couldn't of asked for more, thanks...

### ⭐⭐⭐⭐⭐ Rockville awesome products
*by B***D on May 14, 2018*

So I use lots of Rockville products and I will say that I absolutely love each and every one of them and for the money you can't ask for anything better and any time I build any stereo I guarantee there is Rockville all threw it but getting to just the capacitors, they do their job very well as a capacitor not a substitute for a second battery or a high output alternator like people try to do but awesome as a capacitor hope this helps anyone on the fence about getting one for their system but used probably the same can really help improve your system and prolong all the electrical in your car for those bass heads out there.
