StreetWires ZeroNoise1 Capacitor

If your car's sound system needs a little help on the beat because you're straining your electrical system, then a StreetWires ZeroNoise1 ZN1-1FC capacitor may be just what you need. This 1-farad cap can smooth out the power demand peaks for systems up to 1,000 watts RMS, so the lights won't dim every time your sub hits hard. The ZN1-1FC is rated at 16 volts max (20 volts surge), so it'll handle almost any electrical surge your system may experience, even during peak demand.
