Can a Capacitor Help in your audio System ? Yes it Can help BUT you need to have the supply first . the main part of your electrical is the alternator everything comes from that . your batteries hold that power , your alt will keep you at higher voltage than ur batteries will . here is Test results from a Test taken on the AD1 Amp dyno by the man that Designed the amp dyno. In the tests a standard 1 farad cap. and Carbon 100farad capacitor were used . A Capacitor is a great addition to a Stout Electrical system and is not a Band-Aid for a Weak Electrical system . Capacitors can also discharge faster than any battery in production .
