I have a 760 watt amp powering 2 10" subs and it works fine. my brother has a 1000 watt amp powering 2 12" subs and he got a capacitor. So it really depends on what amp your looking at. if the 760w you wont need one, if the 1000w i would be safe and buy a capacitor. for the 1000w amp you would only need a 1 or 2 farad capacitor.

You need an iron bar, some copper wire and a battery.
How many 12 volts batteries will give you a 1000 watts?
To determine the number of 12-volt batteries needed to produce 1000 watts, you need to know the capacity or the amp-hour rating of the batteries. Divide the power (1000 watts) by the voltage (12 volts) to find the current (Amps) required. Then, divide the required current by the amp-hour rating of each battery to determine the number of batteries needed.
Why you need capacitor?
because it makes you go faster according to gaaabe
Do you need two jumpers from your outdoor condensor compressor to the start capacitor if you only have one and does it need 220 or 120 if it is a 40mfd rated for 330v?
Do you have a dual capacitor that starts both the compressor and the fan motor? You need 230V to power the compressor. You should have one wire from the capacitor going from the start terminal on the compressor and one going from the common terminal to common on the capacitor.

How does a capacitor work?
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them. Inside the capacitor, the terminals connect to two metal plates separated by a non-conducting substance, or dielectric. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper. It won't be a particularly good capacitor in terms of its storage capacity, but it will work. In theory, the dielectric can be any non-conductive substance. However, for practical applications, specific materials are used that best suit the capacitor's function. Mica, ceramic, cellulose, porcelain, Mylar, Teflon and even air are some of the non-conductive materials used. The dielectric dictates what kind of capacitor it is and for what it is best suited. Depending on the size and type of dielectric, some capacitors are better for high frequency uses, while some are better for high voltage applications. Capacitors can be manufactured to serve any purpose, from the smallest plastic capacitor in your calculator, to an ultra capacitor that can power a commuter bus. NASA uses glass capacitors to help wake up the space shuttle's circuitry and help deploy space probes. Here are some of the various types of capacitors and how they are used. Air - Often used in radio tuning circuits Mylar - Most commonly used for timer circuits like clocks, alarms and counters Glass - Good for high voltage applications Ceramic - Used for high frequency purposes like antennas, X-ray and MRI machines Super capacitor - Powers electric and hybrid cars Capacitor Circuit In an electronic circuit, a capacitor is shown like this: When you connect a capacitor to a battery, here's what happens: • The plate on the capacitor that attaches to the negative terminal of the battery accepts electrons that the battery is producing. • The plate on the capacitor that attaches to the positive terminal of the battery loses electrons to the battery. Once it's charged, the capacitor has the same voltage as the battery (1.5 volts on the battery means 1.5 volts on the capacitor). For a small capacitor, the capacity is small. But large capacitors can hold quite a bit of charge. You can find capacitors as big as soda cans that hold enough charge to light a flashlight bulb for a minute or more. Even nature shows the capacitor at work in the form of lightning. One plate is the cloud, the other plate is the ground and the lightning is the charge releasing between these two "plates." Obviously, in a capacitor that large, you can hold a huge amount of charge! Let's say you hook up a capacitor like this:Here you have a battery, a light bulb and a capacitor. If the capacitor is pretty big, what you will notice is that, when you connect the battery, the light bulb will light up as current flows from the battery to the capacitor to charge it up. The bulb will get progressively dimmer and finally go out once the capacitor reaches its capacity. If you then remove the battery and replace it with a wire, current will flow from one plate of the capacitor to the other. The bulb will light initially and then dim as the capacitor discharges, until it is completely out. Farad A capacitor's storage potential, or capacitance, is measured in units called farads. A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amprepresents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt. A 1-farad capacitor would typically be pretty big. It might be as big as a can of tuna or a 1-liter soda bottle, depending on the voltage it can handle. For this reason, capacitors are typically measured in microfarads (millionths of a farad). To get some perspective on how big a farad is, think about this: • A standard alkaline AA battery holds about 2.8 amp-hours. • That means that a AA battery can produce 2.8 amps for an hour at 1.5 volts (about 4.2 watt-hours -- a AA battery can light a 4-watt bulb for a little more than an hour). • Let's call it 1 volt to make the math easier. To store one AA battery's energy in a capacitor, you would need 3,600 * 2.8 = 10,080 farads to hold it, because an amp-hour is 3,600 amp-seconds. If it takes something the size of a can of tuna to hold a farad, then 10,080 farads is going to take up a LOT more space than a single AA battery! Obviously, it's impractical to use capacitors to store any significant amount of power unless you do it at a high voltage. Applications The difference between a capacitor and a battery is that a capacitor can dump its entire charge in a tiny fraction of a second, where a battery would take minutes to completely discharge. That's why the electronic flash on a camera uses a capacitor -- the battery charges up the flash's capacitor over several seconds, and then the capacitor dumps the full charge into the flash tube almost instantly. This can make a large, charged capacitor extremely dangerous -- flash units and TVs have warnings about opening them up for this reason. They contain big capacitors that can, potentially, kill you with the charge they contain. Capacitors are used in several different ways in electronic circuits: • Sometimes, capacitors are used to store charge for high-speed use. That's what a flash does. Big lasersuse this technique as well to get very bright, instantaneous flashes. • Capacitors can also eliminate ripples. If a line carrying DC voltage has ripples or spikes in it, a big capacitor can even out the voltage by absorbing the peaks and filling in the valleys. • A capacitor can block DC voltage. If you hook a small capacitor to a battery, then no current will flow between the poles of the battery once the capacitor charges. However, any alternating current (AC) signal flows through a capacitor unimpeded. That's because the capacitor will charge and discharge as the alternating current fluctuates, making it appear that the alternating current is flowing.
Can you use a 25K capacitor instead of a 2.2K capacitor?
In general, no. You need to use the correct capacitor as designed for the circuit.
Can you by-pass a capacitor in an electric motor?
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
Regarding Capacitors- can any general capacitor work on a circuit diagram that shows a polarized capacitor or do you need a special capacitor for polarization?
A Polarized capacitor means that the capacitor is polarity sensitive. if you were to connect the capacitor incorrectly the capacitor would blow up. A capacitor that is marked as being polarity sensitive will have the negative lead labeled usually with a white strip. These capacitors can only be used in conjunction with a dc source. Always consult a professional when installing electrical equipment.
Do the PSP slim and PSP take the same battery?
The short answer is no. The PSP slim "CAN" take the larger battery from the PSP-1000 series, but it sticks out and you need to get a custom battery cover for it. The PSP-1000 can take the Slim or PSP-2000 battery, but, the same logic follows. It's best to keep the proper batteries to the right console.
Is a diode used as capacitor?
Both a capacitor and battery "store charge". However, in a battery there is a chemical reaction that continues to generate charge. You apply a charge across the "plates" of a capacitor and it will decay over time from leakage or through a discharge resistance to ground in the circuit. You need really large capacitors to store meaningful amounts of charge, to take the place of a battery for example.
