    The capacitor should be a non-polarized electrolytic type rated for at least 16 volts. There is no harm in experimenting with different capacitor values to get a tonality you like. Increasing the capacitor's value will increase the noise reduction but will also make voices sound more bassy. The capacitor is an added load on the alternator, thus stealing current away from your amplifiers and recharging itself. The capacitor severely limits current to the amplifiers while it is charging. It takes milliseconds to discharge the capacitor, but it takes much longer to charge it, especially as it ages in the extreme automotive environment.
