The capacitor is connected to the positive power line to the amplifier, and then grounded to the vehicle chassis. When initially connected, the capacitor will very quickly charge up to the voltage of the vehicle's battery. So quickly, in fact, that a large spark will occur unless a small resistance is used to slow the rate of charge. More on this in a moment.Low frequency causes the output transistors in any audio amplifier to remain on and flowing current to the speakers for a longer period than midrange or high frequencies. Low frequency therefore creates the greatest current draw in any audio system. As the source of low frequency in music is usually a drum or bass guitar, the low frequency is mostly in short bursts, or
