capacitor

magtatanong lang po ako regarding s use ng 2 farrad capacitor sa sound system natin? thanks.

Capacitors

Capacitors are used in most electronic products, and it’s common to see many
of them populating a circuit board. These cylindrical devices store power the
way a reservoir stores water. So when a circuit needs a bit of juice, the cap
releases it. A capacitor is able to deliver power more rapidly than the car’s
charging system because the power capacitor has a lower internal resistance,
which allows it to quickly discharge.

In the early 1990s, car audio sound-off competitors started adding large capacitors
to their sound systems to provide instantaneous power when peaks in a
musical passage demanded it. Before long, car audio-specific capacitors
became available to the masses, and now they are a common sight in most
high-end systems.

You probably don’t need a capacitor if you have a modest system without a
subwoofer, but you could probably use one if your system includes at least
one subwoofer. If you have several amplifiers and multiple subwoofers,
adding a cap or two can definitely improve your system’s performance.

Whether you need a capacitor also depends on how much current your
amplifiers draw from the vehicle’s charging system as well as the type of
music you listen to. If you primarily listen to bass-heavy rap music and your headlights dim every time your system hits a bass note because of the strain
on your car’s charging system, a capacitor could help. (You should also have
your car’s electrical system checked to make sure it’s up to snuff, however.)
Or if you think the total current draw of all of the amplifiers in your system
starts to exceed the capacity of your car’s alternator, you’ll probably want to
add a cap.

Copy-Paste lang bro.

thanks bro. yan pala ang use ng capacitor. important pala kapag may sound system ka. thanks =)

Depende ata yan bro sa bigat ng system.

Madalas gumagamit nyan yung mga boom boom cars. Humihigop kasi ng juice yung bass. Kaya kailangan nila ng extra juice. Kung di naman dumidilim ang headlight mo pag nagpapatugtog ka, palagay ko di kailangan ng cap.

kailangan mo yan sir lalu na pag ang amplifier mo ay 2000w pataas ang power
1500w na amplifier pababa kahit hindi na lagyan ng capacitor yan......
tip ko lang sir.. kung 3000w pataas ang amplifier mo mas magandang gamtin mo na baterry ay 3sm battery....na nasa 60 to 90 ampere.....
at kung ang alternator mo naman ay nasa 90ampere ang capacity ok na ang 2sm battery lng

not true. even if you have a 1000 watt amp but put that on to power 2 or more subs. you will need a capacitor. a capacitor does NOT provide continues power rather STORES excess power. this is for the bass hungry sound setup.

the REAL function of a capacitor is to store unwanted or excess power then to be released when the sound system needs it.

if you have that much power of an ampli and power hungry setup (electrical crossover, more defined seps, etc.), changing the alternator to 120amp and the BIG 3 up grade will help plus the capacitor to STORE power.

sorry to keep on chasing your posts but i have to set the info right for the benefit of others.

maganda yung capacitor na may digital voltmeter.. makakatulong din to monitor your system running voltage.. at least alam mo pag over or under charge ang alternator

Can I use the capacitors used for audio setups in the same way one would use a Pivot Raizin Voltage Stabilizer?

A capacitor would only help if you're experiencing drastic drops in voltage on dynamic ranges. If you're steady at 14.4V and then dropping to, let's say, 12.8V, then a cap may help you. But if you're dropping to 14V, that's simply a waste of cash.

Primary source of power when the engine is ON is the alternator. And unless you're a showcar, keeping the engine ON during SQ auditions is the preferred method. In that case, best to upgrade the alternator to a high-output alternator rather than getting a battery. There are a lot of aftermarket alternators out there. A general idea is that a stock Civic has a 70-80amp alternator, midsize sedans 110amp, if you're power-hungry, there's even 250amps out on the market.

Regarding the voltage, try to keep it around 14.4V. You might think that 14.5 or 14.7V is healthy but in fact it's not as normal systems aren't supposed to be charged with those. Lower voltage = less efficiency = more heat for the amplifiers. So try to keep your amps happy by having a good electrical layout

For a heads-up, if you're mainly into SQ, putting a capacitor is a waste. It's like buying ice when your drink is already cold. If you're into LnC or SPL, you might want to consider them for purchase.
