Capacitors

A car audio capacitor provides power to your amplifier when it suddenly needs more. This category talks about the car audio capacitors and all of their features. You usually see capacitors used in professional car audio systems with a bigger subwoofer setup.

When the amplifier pulls a lot of power all at once the electrical system can’t keep up sometimes. That is when the capacitor comes into the equation. A common sign of this the headlights dimming in time with the bass. A capacitor can help by providing extra power in case the battery fails to provide enough voltage.

A capacitor isn’t always the right fix though. If your electrical system is weak, you’re usually better off upgrading the part that needs replacement instead. We try to be honest about this, so you don’t spend money on a part you don’t really need. Capacitors are rated in farads, and the size you need will depend on how much power your system uses. They also store enough charge to be dangerous. Capacitors need to be charged and discharged with a resistor often.

In this category, you’ll find buying guides for car audio capacitors. We explain things like farad ratings, safety steps, and much more. We try to keep it simple, so you don’t need to know all the technical terms. For each guide, we cover what to look for and the common mistakes people make.
