[QUOTE="gstokes, post: 8282703, member: 660947"] The next time someone tries to sell you a "stiffening capacitor", ask him/her this 1 question.. What's the internal resistance ? The ONLY thing a capacitor that is placed between the amplifier and the battery will do is soak up any AC ripple voltage that gets past the bridge rectifier and provide the amplifier with a cleaner DC signal, AC ripple voltage is measured in millivolts and shows up as noise in a DC circuit but modern alternators have very efficient rectifiers so AC ripple is practically non-existent. A capacitor simply can't charge fast enough to provide any other kind of benefit, this includes the fancy and worthless hybrid capacitors sold by many, there is simply too much internal resistance. The amplifier should have enough built-in capacitance to function correctly and if it doesn't then you need a better amplifier, adding a cap will NOT help.. Here is some excellent reading to help you understand the not-so-magical capacitor [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [URL="http://www.teamswift.net/viewtopic.php?p=54856"]TeamSwift • View topic - Myths Dispelled: Why Capacitors Don't Work[/URL] [/QUOTE]
