[QUOTE="maylar, post: 100183, member: 541144"] I did. The charts and graphs are all very pretty and address the question as to whether or not a high ESR cap is a waste of time and money. But they don't relate to whether a cap presents "additional stress" on the electrical system. A "good" cap will supply peak currents to the amplifier and help prevent the dipping of the terminal voltage at the amp that would normally happen because of losses in the wiring and the alternator's series impedance. The alternator then has to restore the capacitor's spent energy. The cap gives up some of its charge to support transient loads, and the alternator replenishes what the cap lost. Yes, the cap is a "load" on the alternator. But the total amount of energy drawn from the source (alternator) is the same if a cap is there or not. Without the cap, the alternator would have to supply the load directly. With a cap, the alternator has to recharge whatever energy the cap loses. [/QUOTE]
