Description

The Rockville RFC50F v2 50 Farad Digital Hybrid Car Audio Capacitor is engineered to enhance power stability and sound quality in high-performance car audio systems. With an impressive 50 Farads of capacitance, it delivers rapid energy to your amplifier during peak demand, reducing voltage drops and audio distortion. This capacitor features a 3-digit super bright blue LED display for real-time voltage readings, accurate to +/-0.1VDC. A blue illuminated window flashes in sync with the music, while a black wire mesh cover adds a sleek, durable finish. Built-in IC-controlled circuitry provides over-voltage protection at 17.5V, under-voltage alerts at 10V, and warning tones for incorrect polarity connections. Additional performance specs include an ESR of just 0.015 ohm @ 120Hz (25 degree C) and a capacitance tolerance of +/-10%, ensuring consistent, reliable output. Automatic sleep mode conserves energy during low-volume periods. With dimensions of 10.83" x 6.38" x 2.36", it installs easily and integrates seamlessly into most car audio setups. Whether you're a dedicated audio enthusiast or building a competition-grade system, the RFC50F v2 delivers power, precision, and protection in one rugged and stylish package.

  • ⭐️⭐️⭐️⭐️⭐️ A Beast of a Cap — Keeps Voltage Locked
Rockville RFC50F v2 50 Farad Car Audio Capacitor ⭐️⭐️⭐️⭐️⭐️ A Beast of a Cap — Keeps Voltage Locked If you’re running a real system with high draw, this cap holds it down. I’m using it on a multi-amp setup with 3000W RMS and it absolutely helps stabilize voltage during drops. The digital display is bright, accurate, and looks clean on the rack. Easy to install and clearly makes a difference. If you’re pushing heavy bass, this is a must. ... show more

  • Very nice capacitors
The media could not be loaded. I am running two 1600 W amps wired down to 1 ohm. I was having a problem with voltage drops getting down into the low 11 volts. I wired two capacitors into the system. One for each amp. Now I don't have the voltage drop issues that I used to have. The light show on the capacitors looks nice, but it isn't timed with the music. I would recommend these they seem to be very solid. ... show more

  • Seems to work fine for now.
The media could not be loaded. Seems to do the job. I’ll need to keep an eye on it the next few weeks but it works.

  • not great...update.....doing the job now
looks nice...thats about it. i got this for extra power..have extra battery etc.....this does very little..def NOT 50 farad, maybe a 1k or 2k system...but the 6k....just a led light! just not effective. upon further review....it was charged incorrctly!!!! have all wiring upgrades. extra battery alt etc....getting volt drop..14.3 to 12.9....added this(charged correctly) 13.9 at the lowest so far!!! so for the money...solid! i got tarampd 5k, 4 5stack 15s...8 8,8 6.5, ...8k total watts....solid ... show more

Did not meet expectations and does not work as it’s supposed to would not recommend at all

  • Awesome for my needs
Using for power support for a 6000 watt amp pushing 4 dvc 12” subs and a 800 watt amp pushing 2 10” dvc subs all running at 2 ohms and a a crossover with an epicenter and I’m never starving for power! Perfect! If I expand this system I will simply ad another one of these caps! Incredible power support from a relatively small component. This system is a beast and probably registers on the Richter scale😵💫 ... show more

Seemed to work. A little confusing on the instructions. The video the send a link to is for a different one and don’t make a lot of sense.
