Car Audio Capacitors

When you have a big subwoofer in the car, you need to make sure it’s getting enough power. Larger subwoofers use so much current that they can leave other electrical systems at a deficit. The loudest bass notes can cause the headlights to dim or the windshield wipers to pause because all the power is being used by the music.

That’s why installing capacitors for your car audio system is a must if you have an aftermarket subwoofer. A capacitor can quickly store and discharge energy when it’s needed. In a car stereo, an outboard capacitor will provide a jolt of power to the amplifier during bass peaks and other surges. This ensures the rest of the electrical system has the power it needs so your music doesn’t prevent you from seeing the road.

Increase Your Power Capacity

If you’ve noticed the lights dimming whenever the bass gets down to business, add a high-quality stiffening capacitor from OnlineCarStereo.com. We stock many different digital capacitors depending on your current subwoofer and amplifier. Those who only see a flicker on the biggest of notes will be fine with a 1-farad, 2-farad or 4-farad capacitor. If your lights are regularly losing brightness or cutting out entirely, we offer 10-farad, 20-farad and even 30-farad capacitors for energy storage reinforcement. Most capacitors have a digital voltage monitor so you can see how much power is stored. They also are constructed with over-voltage protection circuits to prevent frying your amplifier or speakers with too big a jolt.

An Affordable Power Surge

Those who can’t afford a new amplifier, or who don’t have the battery power for it, can find a lower-priced solution from our selection of car capacitors. We are an authorized dealer for every major manufacturer of car audio accessories, including Boss Audio, Massive Audio, DB Link and Lanzar. Get a capacitor that keeps you powered up with free shipping on everything!
