Do your headlights flicker when the bass hits hard? Does your bass start out strong, and then fade into mush after a minute or two? Car batteries are slow to deliver the kind of power your amps need to give you tight, powerful bass hits.Impulse capacitors eliminate that problem by storing reserve power and then delivering it lightning-fast just when your amps need it most. That s why you see external capacitors in just about every stereo competition vehicle &mdashand you don t see dimmed headlights.Impulse Caps act as a buffer zone between your amp and your battery, getting the juice to your bass for maximum performance. The Impulse PCA1500 1.5-farad capacitor can be used with amplifiers producing up to 500 watts RMS.1 year warranty
