Power Acoustik PCX‑5F – 5 Farad Digital Power Capacitor for Car Audio Systems
The Power Acoustik PCX‑5F is a high-performance 5 Farad digital capacitor designed to stabilize voltage in car audio systems during heavy bass peaks. Engineered for demanding sound setups, it functions as a stiffening capacitor by delivering rapid bursts of electrical energy to your amplifier, reducing strain on your vehicle’s electrical system and minimizing headlight dimming.
This capacitor operates within a 12–16 V DC input range and utilizes an internal foil-carbon hybrid construction to maximize charge capacity and energy delivery. The integrated top-mounted digital voltage display provides real-time monitoring of your system’s voltage levels, allowing for precise system tuning and quick diagnostics.
Whether you're running a single monoblock or a multi-amp configuration, the PCX‑5F enhances current flow and stabilizes voltage drops that occur during deep bass hits or high-power audio bursts. The internal voltage and polarity protection circuits help shield your audio components against spikes and miswiring, while the LED accent lighting adds a sleek, illuminated touch behind smoked Plexiglas housing.
