Check out http://www.google.co.uk/search?hl=en&q=define%3A+capacitor&meta= Also plug your beer can cap into your battery, disconnect it and put your finger across the polls :P. Then tell me that they don't hold charge. [Edited on 14-08-2006 by AaronHorn] | |

yes - current smoothing and removing spikes......thats all an external one will do...the amp capacitor is plenty, | |

Urgh, whatever you do, don't run an earth wire. Not only is it a waste of money you're just going to be picking up more engine noise and interference. The point of earthing through the chassis is that everything else also earths through the chassis so the potential between all electrical components in the car is 0. If you run wire you could end up with a potential difference between your head unit and amp, then you get noise. | |

At the risk of being ganged upon as i know people on this site dont like power caps i think power caps are a personal preference. What you need to ask yourself is what you want from your system and how far your prepared to take it. What a power cap does is not save your battery power youd need a second battery for that it just evens out the flow of power from your battery the advantage being less strain on your battery and faster supply of power to your amp. I do agree however that for a system like yours you probably wont need one its more for competition systems that are trying to fine tune there system. Remember if your struggling for power abc upgrade in this order - alternator, battery power cap but as i mentioned before i dont think you need to take it to c. | |

0Gauge all way from engine to distroblock. then got 2x 4Gauge out of them, whtta will be less then 1M so il be fine, then the earths joing to a disto block with 4Gauge wire and then out the distro block to 0Gauge to the main earth | |

By 100A, I presume you mean fuses, you should have the lowest rated possible with fuses, maybe 100amp at the engine side is fine but I'd be tempted to go with lower values for the 4 guage wires coming out of the distro but then according to http://www.mmxpress.com/technical/wiregauge.htm, 4 guage can carry 100+ amps when the length is <1m so you should be fine with 100amp since presumably you're amps will be fused to their designed specs. | |

waste of time on any system ,better off putting money into deisel alternator and battery, pick alternator up at scrapyard for £20-£30 battery £30-£50 | |

Power caps are kind of stupid I think, fashion accessories if you like. Indeed they can help if your head lights are dimming but otherwise they woun't do much. You have thick wiring and presumably a decent battery so you are unlikely to need one anyway. What I would say is ensure your ground wiring from battery to chassis and chassis to distro is also good and thick. | |
