Wow




Pretty sure I asked a simple question of how long i should get my cables so that i could run a power line from the battery to my trunk and get some xtra for the cap that i bought at a discounted price so i thought wtf, and decided to put one in my system.

I didn't mean to start a raving war about the exact necessity of a cap, its my first time using one, so i am trying it out...gosh i'll do what i want.

Thanks for all the xtra info on how they effect the electrical system tho...

 

CyRaX2007 - haha, they did kinda go off eh?

20ft should be good ;)

oh, and PS. mr exact science...

"Look at the joules of energy the cap creates."

i didn't know caps CREATED energy.. thats pretty sweet, i should jsut get a bunch and subercharge the tC with it.

Holla!

 

Your question was answered earlier in the thread, but it evolved, as lots of threads on message boards do (I'm sure you'lllearn that, or ahve already found that out from being on them). I'm not fussing, I'm not mad, I'm pointing out something, Sciondad (at least I think this is what he's attempting to do) and myself are having a debate based on our experiences, knowledge we've obtained, etc. An intelligent debate,if you will. If anyone gets mad, well, that's their prerogative. The way I see it, arguing on the internet is like the Special Olympics, even if you win, you're still retarded. That doesn't mean that we can't put our opinions out there, and leave the rest for people to make their own decisions.

 

for sure, there is a lot of sharing of info, which is always good!

 

Now that made me laugh. I sure hope no one is upset. It's a discussion and one in which I enjoy if I have time. Good information flow. You spoke of cap resistance and inductance also known as ESR and ESL.

ESR is the equivalent series resistance of a capacitor. An ideal capacitor would have only capacitance. As you remember, all conductors have resistance. In a capacitor, there are multiple conductors like the wire leads, the foil and the electrolyte. The resistance of all of the conductors contribute to the capacitor's series resistance. It's essentially the same as having a resistor in series with an ideal capacitor. Capacitors with relatively high ESR will have less ability to pass current from its plates to the external circuit (to the amplifiers in the case of stiffening capacitors in car audio). Low ESR is desirable when using a capacitor as a filter.

ESL is the equivalent series inductance of a capacitor. Since most electrolytic capacitors are basically a large coil of flat wire, it will have even more inductance than it would have if it were flat. This inductance, along with the small amount of inductance from the wire leads, will make up the ESL of the capacitor. The ESL is essentially the same as having an inductor in series with an ideal capacitor. Low ESL is desirable when using capacitors for filtering purposes.

 

I'm well aware of ESR and ESL, but I really didn't want to confuse anyone here by using the abbreviated version. Good to know that someone would have known what I were talking about had I used that terminogoly. Clark's data (what he refers to as his cap lessons) go into great detail on ESR and ESL. But again, that's a long set of information (which I actually think I've already posted elsewhere in a thread I posted titled something like "Car Audio Basics" or something to that effect).

Regardless, I think we can agree that caps, in certain situations, can be effective to combat dimming.

 

^^^ I'm not saying you are right or wrong, but quoting Richard Clark gets you no points...you actually *lose* points by quoting that @$s clown.

I have a hard time listening to a so called expert (Mr Clark) who used to promote caps, and the benefits they provide. Now, 15 years later, he's gone wishy washy and he dismisses them because they don't work to his requirements???? Which view of his am iIsupposed to listen to?

You can follow Clark around all you like, and be a Richard Clarkbar disciple, but quoting him like he is god isn't going to win you any points in my book. not that this was your aim

 

___ clown is a funny word! ha ha!

 

Yes, Dick...um, excuse me, Richard Clark is well know for his um, lets just say, waffle approach to caps over the years. Glad I'm not the only one aware of his long track record.

riccochetrabbit, I agree that caps can be of some benefit in certain situations and dimming can be one of them.

 

Dimming is the only one they're good for. As far as Clark, he's always (at least to my knowledge, and reading several of his books, and other writings, along with his emperical data from his research over the years) been an advocate of caps being useful for dimming, but that they do not improve voltage. I could be wrong (as I'm only 22, and haven't seen all of his writings, nor do I plan on it). It's just from reading his writings that I have,studying his data, etc seems to work mathematically for me, and I tend to agree with it. Does it mean that I'm saying it's 100% right? Nope, because there are probably errors in it, and his methods, math, etc, but I haven't seen anything, nor have I done any works that's ever proven it false. Works for me.
