what does a capacitor do for a stereo system?

[rendog24]

i ahve no ieda what it does. does it produce more power for the subs, amps or what?

Speakers use electricity from you battery to create sound.
What a cap does it when the amp requests a large amount of power (usually for low bass notes) sometimes it takes more then the batt can supply in the amount of time the amp needs it. So your low bass notes are not as full as they could be because of lack of power.
A cap holds some energy in it for this and releases it so the amp is never starved for energy and thus your bass responses are fully developed.


hope this helps.

Oh here for a Professional responce...

I'd like to mention that a capacitor is basically a [cheap (not really)] quick fix for providing more power to subs. A better solution is to rebuild the stock alternator or... get a higher output alternator which will always provide more than enough power.

a capacitor smooths out voltage fluctuations and helps to deliver quik bursts of above average power when called upon. while a huge bass note will bog the slowly responsive lead/acid battery a cap made from paper and chemicals will be able to deliver that power much more quikly.

if you wanna help your system then start with the bottleneck most people overlook. the factory battery and engine grounds. if your headlights are dimming 9 times out of 10 replacing the battery ground with a thicker wire like a 4 gauge wire will eliminate it. trust me its worked on every car ive tried it on that didnt have really bad dimming. i mean if you look at all the red coming off the battery and there is this single skimpy black wire that should sound the sirens right there. plus it only costs about 5 bucks for wire if you dont have it laying around allready.
