Rockville RXC4D 4 Farad Digital Car Capacitor Blue LED Voltage Display Power Cap

Today’s car audio amplifiers need huge amounts of current. Often a vehicle’s electrical system is unable to provide it. With your car’s air conditioning running, the factory electrical charging system may already be operating at only 70% of full capacity. When a bass note hits or when playing your system very loudly, there may not be enough electrical energy to power your amplification system properly causing your music to sound strained and distorted. Rockville capacitors are designed to store enough electrical current and to release this energy extremely fast due to their superior design and low internal resistance. In addition, as quick as your amplifier needs a new current surge, your Rockville capacitor will provide it. This continuous cycle of power discharge and recharge guarantees flawless bass playback.

    Claims to be 4 farad, performs like 1 farad. The general rule of thumb with capacitors is 1 farad per 1000 watts, and the unit resolved my headlight dimming issue while using my 600 watt max output/200 watt RMS mono subwoofer amp but upon upgrading to a 2 channel amp with the same specs (600w max/200 rms x2) the capacitor failed to manage the AMP draw. I’ve used other 4 farad capacitors with higher wattage amps without issue but decided to try this brand out because they seemed to have good reviews and a nice price. Unfortunately I got…

    IF YOUR SKEPTICAL ABOUT CAPACITORS, THIS ONE WILL MAKE YOU A BELIEVER! I have always been skeptical of capactiors and if their even useful. Switched out my kenwood 12 in subs with some rockville v2 putting out more power then my car could give. Radio would cut out at basedrops, starting having all kind of electrical malfunctions(lights dim, tachometer lights turning off and on, blown headlights, and finally heater quit working in car. Hooked this up and all those problems went away can play speakers on max volume with no distortion or cutting out… And It sounds…
