To determine the appropriate capacitor size for car audio, calculate the total RMS wattage of your amplifier system and use a general rule of thumb: 1 farad of capacitance per 1,000 watts RMS. This helps stabilize voltage and improve performance by providing quick bursts of power during peak demand. Consider going slightly higher in capacitance if you frequently experience dimming lights or voltage drops.
