Does size matter?

Bronze Member Username: HeadutterPost Number: 56 Registered: Jul-05 | Are there better, quicker reacting caps, than others. If I need a 1 farad cap for a JL 1000/1 which cap is best? Does size of the cap increase it's efficiency or is there a point of over kill? |

I'm only running a 1.2f cap, and am running over 6k peak... Hrmmm... Guess I should look into getting some more/bigger capacitors, heh. Any advantage to say two 3 farad caps, over six 1f caps? Or vice versa? Seth |

Bronze Member Username: HeadutterPost Number: 57 Registered: Jul-05 | The amp is 1000 watts RMS, not peak. Peak could be 2000 watts. So do i need something bigger? Are some capacitors better than others at reaction time? |

Gold Member Username: CarguyPost Number: 3905 Registered: Nov-04 | If your amp is 2000w peak and you are using 1F, then yes, you need additional 1F. Seth, you can get 6 1F or 1 6F. It doesn't matter cause they will add up in total. All caps are made the same. So they will behave in a similar way. Some you see that are 2x or 3x the cost of another. That is just bs advertising and brand expense. Take a look at power wires. You will see one that's $100 and another no name with exact spec for half the price. All packaging and Name. |

Bronze Member Username: HeadutterPost Number: 58 Registered: Jul-05 | Does anyone know the peak wattage of a JL 1000/1? JL does not list the peak output wattage, so I don't know what it is. If it turns out I need a larger,(say 2 farad)capacitor or (2) 1 farad capacitors how do I connect them in parallel or series? |

Gold Member Username: CarguyPost Number: 3907 Registered: Nov-04 | The peak can range somewhere between 1.4x - 2.4x the rms. So for 1000w, it's safe to say 2000w peak. You connect the caps in parallel, pos to pos and neg to neg. |

The speed of the capacitor is stated by it's ESR. Generally the higher the ESR, the slower the capacitor is going to be in response times. http://www.wickedcases.com/caraudio/capacitors.html |

Bronze Member Username: HeadutterPost Number: 59 Registered: Jul-05 | Ok, so the higher the ESR the slower the response times. Give me an idea of the range that the slowest to the fastest fall into. I don't know a base line to start with. Is there a particular brand that falls into the better, faster catagory or is it like cars in that GM makes Corvettes and Chevettes? |

Gold Member Username: GlasswolfWisteria, Lane USA Post Number: 9262 Registered: Dec-03 | not a whole lot really. they act as a smoothing filter, but they won't help if you lack sufficient current from the alternator. http://www.wickedcases.com/caraudio/capacitors.html |

Bronze Member Username: James_gTN Post Number: 61 Registered: Jul-05 | Thanks. I wasn't sure what they really did, but I did know from reading all these messages that they didn't solve voltage problems like so many people claim. I told a co-worker last week I was ordering a HO alternator for my 4-Runner and he suggested just getting a cap. I wasn't able to give him details, but I did tell him a cap could not make up for a HO alternator. Now I can explain it better. |
