  • ⭐️⭐️⭐️⭐️⭐️ 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

Stay away from this abcdefg what ever fancy name they wanna name this 0.000 farad capacitor, waste of time doing all the research and hooking up it does not work, what’s sad is it is on a 800 watts and it is dimming exactly the same, just spend the money on a real capacitor because this stuff is a waste of time, sorry I’m being negative but this is the kind of things that we need to shot down they factory ... show more

  • 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
