The Role of a Capacitor in a Car Audio System

You've got a slammin' new complete arrangement in your vehicle, right? But accept you anytime noticed a aberrant aftereffect that happens whenever the bass band punches up to maximum? The car lights dim; the top end drops in accuracy and clarity, and the complete may even get a little..."fuzzy."
Congratulations! You've just entered the abridgement zone. All these furnishings (and more) are all acquired if the ability needs of your complete arrangement amplifier are greater than a simple car array can provide. After all, your array isn't annoying about accouterment the best ability to the amplifier that is blame the subwoofers speakers that accord your arrangement its best bass response. No, it's anxious with atomic issues like befitting the engine running.
So what to do? Like Captain Kirk on the Starship Enterprise, you "need added power!" And that's area capacitors appear in. Unlike a battery, area ability is stored up and appear in a slow, abiding beck of juice, capacitors abundance up electrical activity and absolution it in able jolts. Mounted appropriate next to your amplifiers, capacitors (also accepted as "stiffening capacitors" because they anneal the backbone of a billowing bass response) accommodate the added electrical addition appropriate to drive the subwoofers speakers if the ability they charge is getting sucked off by added systems (like the headlights or the neon basic trim).
So how do capacitors accomplish this phenomenon of ability punching? It's all a catechism of resistance. Attrition is affectionate of like an activity floodgate; it determines how fast or apathetic ability can access or leave an electrical accumulator system. Batteries abundance electrical ability boring and absolution it boring because they accept a top akin of resistance; the attenuated floodgate agency that it takes a while to pump a array abounding of juice, but it aswell agency that it takes a while to cesspool the abstract out of it. Capacitors accept a actual low resistance. They can be abounding with activity actual rapidly, but the amplitude of their "flood gate" agency that this activity aswell releases in a blitz as well.
Why don't we use capacitors to ability everything? Simple; if we did, you'd about-face your arrangement on, it would ability up with ablaze sound, thumpin' bass and bland midrange for about twenty seconds-then all the ability would be beat and your music arrangement would die in the aboriginal two confined of the latest Coldplay cut. Batteries accord you smooth, abiding ability that will get you through the accomplished anthology and into the next brace of hours of agreeable enjoyment. The bolt is if a abrupt advance is bare to drive your subwoofers speakers harder than the crawl of ability a array can provide. A stiffening capacitor detects this bead in ability and releases a compensating blow to ample the gap, befitting ability levels analogously top and preventing that billowing bass and abridgement of accent that wipes out the absolute music experience. Stiffening capacitors are to your complete arrangement what appearance is to Popeye-that abstruse activity antecedent that keeps your music "strong to the finish!"
So the next time your subwoofers speakers are sagging, ability for your complete systems' own claimed spinach-stiffening capacitors-and get the blastin' bass that even Bluto Blutarski would envy. You'll be animated you did.
