A capacitor supports your vehicle's electrical system when used with an amplifier to ensure your amplifier gets the power it needs when it needs it without overtaxing the battery and alternator. The CAP1D is a 1 Farad capacitor designed to be installed between your vehicle's battery and amplifier. The capacitor stores power internally and delivers it to the amplifier ensuring proper function especially under high volumes or excessive bass. The CAP1D includes a digital volt meter that shows how much current exists between your amplifier and battery.
