Capacitors .... Do they work ?? Time to stir something up REAL bad :-)

[blue 10+ year member]

caps work in the right conditions. people around here run to much power, etc, to make use of a cap. imo.

Good point Bro .... There is definitely a point in which NO cap would work. Just for kicks though , I'd like to see what one of the 35 to 50 farad caps could do with a system of several thousand watts .... If anything.

Third : Since the head unit IS a DRZ-9255 , it IS putting out a true 8 volts without clipping, as it has non-clipping outputs , you IDIOT.

I was under the impression that a DRZ had a 4volt output...

You must have gotten confused, it has 8 channels of output, but at 4 volts. It's not an Eclipse. Don't worry, I wont call you an idiot.

The DRZ has an 8 volt output on the sub channels when the volume is at +6 , 4 volts on the other channels, and 4 volts on all channels when the volume is at 00 ( reference ) ..... Obviously, the dimming problem came from the subwoofer .... So therefore the 8 volt reference still stands as in my original post.

At least this is what is stated in the Spec section of my owner's manual .....

It says in the owners manual that at +6 DB it can reach a max output voltage of 8v. It doesn't say anything about subwoofer section, but it does say that it is 8V at 1k HZ.

And how exactly was this story so earth moving, so life changing, so perspective shattering, that you needed to create an entire new thread to tell it?

Theres threads about why shit is green sometimes...hows this worse than that?

....even if the cap did stop the dimmage...............keep playing the system full tilt for another 15 min and when the batteries dont have any extra juice left, and the alternator is working as hard as it can, the cap wont do shit for dimmage once there's NO EXTRA JUICE...ive had caps help and not help before in my past setups...as some said before sometimes they work sometimes they dont, sometimes they work for the intended purpose, sometimes they dont

either way im pretty sure if this cap helped with dimmage right off the bat, just give the system a lil time to drain itself and youll get the dimmage back.....caps dont create extra juice, HO altys do //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

word.

never HAD to put one in. on the honda, we got an x600.1 pulling its 60amps on a 60 amp alty WITH the BIG 3 done and there is still dimming before 'full tilt' on music. there is however just a cheapo 50 dolla autozone batt that is tiny as shit. with that replaced by a bigger yellow top im almost positive there will be little to none from it being able to take the draw. now i could throw a cap in there and itll PROBABLY stop it too but that wont FIX what the problem is.

Two days later , and I have NOT received any word of the dimming coming back , and believe me , I WOULD definitely hear about it !

Matter of fact , we had a 45 minute drive to the airport with the music playing LOUD the entire trip , and had NO dimming.

That's all according to exactly WHAT you are trying to fix ..... If your goal is to stop the headlights from dimming , and it does indeed do that , then you HAVE fixed THAT issue.

Thank you .... That's what I was remembering reading then. My point really was the head unit's output voltage was maximized in the gain setting scheme of things.

There was no experiment , only a point : The capacitor worked to stop the dimming headlights in his system.

Lawls. Go back and reread his question. Please answer that. Reading destroys you...//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

He he he .... I just loooove to stir things up from time to time //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif//content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gifThe debate over whether caps really work or not , is ALWAYS hotly debated. I'm not posting to open up a technical discussion , but rather tell of my experience this past week , and let YOU decipher what you want from it.

One of our fellow forum members hired me to fly to his home and install a competition level system in his new car, as well as provide the equipment. He purchased a great 1500 amp Odyssey Dry Cell battery, but his stock alternator is only rated at 80 amps !!! He's using three amplifiers in his system. One is bridged in to 2 ohms at 1400 watts on a sub. One provides 270 w/ch to his 6.5" drivers , and one is 170 w/ch for his tweeters ... That's a total peak output of 2280 watts .....

With his head unit's high 8 volt output , the gains on his amps are set at almost dead minimum , and yet the system will still play louder than a person really wants to listen to for long. Point is : His gains are set properly ....

He's using 1/0 power and ground wire , and the Big 3 were also done.

He went for a test drive and had VERY , VERY bad pulsating headlight dimming. WAY too much to be acceptable.

Now ... I reccomended a high output alternator , but he didn't like that idea at all at first. So after speaking with me about car charging systems , he decided to buy a Stinger Hybrid 10 farad Cap .....

After the Cap was installed , he has NO MORE DIMMING HEADLIGHTS !!!

Simply put again : You be the judge , but in this case YES .... A cap worked.

As a last note , he ended up finally deciding to go ahead with my suggestion and also buy a high output alternator that he should have in a couple of weeks .....

Cheers , and let the debating begin //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif :laugh: //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I got to the highlighted-in-red statement and quit reading.

So you're telling us that someone on this forum hired you to fly to their house and do an install??? C'mon...who? Why? I'm having a bit of trouble buying into that particular bit of lunacy...

caps are poop... they actually hurt you in spl comps. its been proven...

regardless of this situation, a capicator is a bandaid to an existing electrical deficancy when related to dimming headlamps. obviously car manufacturers dont install an alternator in a vehicle with more than are20% (or so) percent 0ver t0lerance. so his stock alt supplies what? you said 80 ampres? so his car in theory should use 50~70 ampres? even with the capicator, the electrical system is being overdrawn, and the alternators electrical induction is forced at maximum. so the windings on each side of the generator are warming up rapidly and will most likely end up shorting out or burninng up the regulation circuit.

the problem is NOT the dimming, but that is what is noticeable. the PROBLEM is that one of these days your car wont run becacuse the charging system is going to fail and the owner spent the money on a bandaid rather than a solution.

so you installed one of these? wow. steep price!!

why not go with this for a few more dorras? (assuming you buy one for his make\model)

so in recap-

capicators will fix dimming sometimes. yes. is dimming the real problem? no, no its not. dimming is an indicator that should make you realize there isnt enough recharging power in your electrial system to run the car, stereo and headlights at the same time.

BUT - capicators are useful in some situations, such as the voltage regulation situation. they do have a good amount of capatance and will steady the input voltage from the alternator wich is a good thing, but IMO thats all they are good for.

and on a second note - regardless of weather or not your headunit has 3v, 8v, or 24v preouts, that is the MAXIMUM output voltage. we all know that audio consists of AC frequency cycles, so maybe, just maybe, a cycle in the track will reach maximum amplitude and the volume on the headunit will be at max, and it MIGHT output 8v for a milisecond. so a "true 8v" means it CAN, not that it will be there at a constant 100% of the time. get a voltomitor and set it in series with your RCA's and drive around for a week. tell me if it ever reached 6v and ill be suprised.

and that is my 2 cents.

is it? in what way? i'm not planning to join any spl comp in the future, but i am planning to use this for design/look purpose...
