capacitors?

jlman,

First off there is no need at all to get nasty with you reply. If you are going to start trash talking atleast learn how to spell first! You must not be able to read either because if you did then you would know that I'm talking about an ISOLATED battery and NOT the battery that you start your vehicle with!!! I also never in any of my posts claimed that this battery would last for all of eternity! If anybody thinks that a battery can last forever then they are just plain stupid. I thought everybody knew that and figured that didn't need to be stated, but I guess not. So now that I cleared up the fact that the alternator is NOT hooked up to the battery in the situation that I'm talking about, and that I'm talking about an ISOLATED battery we can go full circle to where this battery is getting its power from. First off I'm in the process of finding exact numbers as to how long this battery will last on, lets say, a 1200watt amp... I'm sure it lasts more than 30 minutes of listening time! This ISOLATED battery will obviously not stay charged forever as I have already stated above so guess what? That means your going to have to charge it when it goes dead. This is also a common sense idea, but I figured I state that also for those who don't have that. Does that answer your questions? If not, feel free to explain how an alternator can charge a battery that is never connected to it!

Your right!! it has gotten way out of hand! It is kinda funny though

I'd say the answer to the capacitor is a no.

Hook up the system, if the lights dim then look into a high output alternator, its definately a great investment since we all know in car audio you can never be happy with the power you have, you will definately upgrade to a larger system in the future, everyone has suffered this bug, and when that opportunity comes to upgrade you wont have to worry about the charging system since you took care of it when it was needed.  Believe me, the people on this board with over 1000 posts have been newbs also, but we have learned our lessons which is why when we/they make a point were not going to stand down since were like your old man who knows all and thats it, no excuses lol.
