kopke Posted March 27, 2011 Author Share Posted March 27, 2011 This has nothing to do with how you write. This has to do with the sort of basic questions you are asking, which indicates lack of knowledge in the matter and you are playing with hardware that can kill you. Please don't become a Darwin award winner. Let someone that knows what they are doing handle your work. You are looking down the barrel of a loaded gun. Don't know about you but I like to lern stuf.

Miro Posted March 27, 2011 Share Posted March 27, 2011 Don't know about you but I like to lern stuf. Fair enough, but there's different approaches to learning. For this particular subject, I think it would be best for you to learn by observing someone who has done it before, and have them install it in your car. Yes, it's not as hands-on as you'd like, but again -- you're dealing with a device that could kill you. If you accidentally touch the charged capacitor's positive terminal with one hand and the negative terminal with the other, you could die. If you accidentally bridge the terminals with a screwdriver, you could die. If you install it improperly in your vehicle, it could explode, and you could die.

Th3Franz Posted March 27, 2011 Share Posted March 27, 2011 A capacitor by design is used to stiffen voltages. They work effectively for car stereos to maintain voltage as high-power amps cause a voltage drop during transient situations when the bass hits. A mis-handled "4 farad" 14.4V cap won't kill you but it could leave a nasty burn. Use a resistor to limit the amount of current to the capacitor. You want to hook up an RC circuit with large resistors to limit the current. A 1k-ohm resistor in series with the battery with a 1k-ohm resistor in parallel with the capacitor should be sufficient. http://www.caraudiohelp.com/car_audio_capacitor_installation/car_audio_capacitor_installation.htm -Franz The end of a Legacy http://www.youtube.com/th3franz Link to comment Share on other sites More sharing options...
garbo41610 Posted March 27, 2011 Share Posted March 27, 2011 I used to love it at TAFE (apprentice school here in Aus) we would charge up small capacitors, I'm talking microfarad caps, and throw them at someone when he wasn't looking. Great times had by all in that class LMAO. Link to comment Share on other sites More sharing options...

lossol Posted March 31, 2011 Share Posted March 31, 2011 I have calculated that a VBG1 could run off of a 4Farad cap:eek: for about 6.5 minutes. The link http://www.caraudiohelp.com/car_audio_capacitor_installation/car_audio_capacitor_installation.htm is a good one. They explained that it's safe to pre-charge the cap with say a 1k resistor. If you run the calculations over here http://hyperphysics.phy-astr.gsu.edu/hbase/electric/capchg.html You will find that it takes a very long time to charge through a 1k, but they suggests that so you don't cause peak currents to get crazy. Once it's charged it's safer to hook up directly b/c the peak charge currents will be much lower. Peak charge currents of 4Farads directly to the battery would be in excess of 140 Amps assuming direct connection of about .1 ohms. Yikes. 4 Farads!

mwiener2 Posted March 31, 2011 Share Posted March 31, 2011 So what you are saying is that If I take the capacitor out of my camera flash, it probably has enough juice to fill in the quarter second or so of voltage drop from my sub.
