Without knowing your sytem power requirements, how many amplifiers and how big they are, etc, it is hard to give a definitive answer. However, if your headlights dim on large bass hits, or worse yet are "dimming with the beat" then it's pretty safe to say that you do need a cap.
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.
when i play music in my car the lights dimm i wanted to know if a capacitor would stop that problem
Very carefully
Positive post of capacitor is connected to the heavy amp cable. The ground terminal (or case) of the capacitor is connected to the car's ground or a ground wire that leads to the car's chassis. That's it.
can,t be done with a capacitor alone current only flows when a capacitor is charaging or discharging. capacitors are used in motors for diffrent reasons some are cap start or cap run, or for power factor corection. you should make sure any capacitor is replaced with the correct voltage and amp rating.
To calculate the capacitor size needed, you'll need to know the amplifier's voltage requirements. Then you can use the formula: Farads = Amps x Seconds / Voltage. If you provide the voltage requirement of the amp, a more accurate calculation can be done.
if you use a uncharged capacitor most likely your car battery will drain much faster using a uncarged capaciter will mess up your amp good power source is needed for your amp to give its maximum potential for deeper bass and no dimming
The capacitor will not cause dimming, whatever it is that the capacitor is being used for (usually helping drive a bass amp) is what causes the dimming. A capacitor is a quick charge and quick discharge battery basically, so when the amp has depleted the power in the cap it still must go to the car battery for power and that is when there will be dimming lights.
dude you just need to get a bigger amp n a capacitor...i got a 1600watt pheniox gold for my two 12in cvrs n that powers them plenty. yes u could use a bigger amp to solve ur problem but the reason is most likely the ohms its probably unstable but i would need to know the way that u have the subs and amp set up together.
the capacitor has 2 wires or poles, one is the ground or negative and the other one is the hot or positive... if it is for car audio amp the ground is connected to the chassis and the positive is connected to the battery and to the positive wire of the amp.
the amp wont work.Check the power fuse first.If this is ok, there is generally another fuse inside the amp that will need checking
paper capacitor
