[QUOTE="2theMaxx21, post: 126484, member: 546337"] No, you won't hurt it. A charger doesn't force current into a battery or capacitor. It only fills the battery with whatever current it will pull. When the battery is charged, it no longer has any uneven potential energy, and the cells are fully positively charged. The only way to hurt a capacitor is to put too much voltage to it (over 15 volts) or if you get the polarity switched around and hook it up backwards (explosion). But if you really want to be safe: If you have your sound system wired correctly, you should be able to disconnect the fuse near your battery that is inline with the power wire to your sound system. Then your amps and your capacitor will be disconnected from your car's electrical system. Your capacitor should not be directly connected to your battery. There should be a fuse inline somewhere (preferably near the battery). [/QUOTE]
