Your cart is empty. 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 "transients". So subwoofer amplifiers generally draw the most power from an automotive charging system.
This power "reservoir" in the capacitor only works to a point. If the power draw from the amplifier or multiple amplifiers demands so much power that the alternator can't bring the charging system and capacitor back up between bass transients, then reduced bass response and flickering lights will again occur. Adding more capacitance may help, but an alternator with a higher current rating would be a better solution.

For the cost of this product it’s definitely worth it. 6 months strong with no issues!

Not sure if it was the product or my lack of knowledge installing it but the digital numbers never came on. It doesn't charge but does bypass the remote wire. I suggest watching a video on how to install a audio capacitor before installing if you do not know how to in the first place.

No remote wire for volt meter. Will eat your batt dead. Tested with multi-meter, only holds small charge, dissipates fast. Maybe a .5 farad. Get what you paid for. Trash 🗑

The product only worked 5 minutes then display went off and never came back on wasted more time installing then actually worked

I'm no professional car audio installer so it was very helpful this came with a step-by-step guide on how to install. If I ever need another for a different car I'll be buying this again.
