Capacitor

[Ace Ventura 10+ year member]

ok, ive done some testing with one, my voltage dropped 3v MORE with a cap, than without one. so do you believe me, i did testing too... anybody can say some garbage like that. i dont believe your 10.5v vs. 13.5v at all.
that $100 can buy you a big *** everstart battery at walmart to add as a secondary battery that will work wonders with 1500rms compared to a cap.

What would you suggest i do running over 4kw rms? should i get like a 4 farad cap along with 1 battery up front? will that be enough? lol (since 1,000w needs a 1 farad capacitor according to manufacturers)

You sir, dont know shit.Only time i've seen a cap used for a good reason was wired to a relay so that when voltage went dropped low enough to shut the amp of, it stayed on

which is a retarded use for a retarded piece of equipment

Buy a battery, leave the caps to those dumb enough to buy em from the snake oil salesmen at best buy

I've used caps on at least 3 occasions with good results EVERY time.

Say what you will.

But I've never experienced a 3v drop..Something wrong there.

And I don't have experience w/ that much power so I won't try to act like I know what I'm talking about.

I ran a 1 farad stinger cap for my 1,000 watt amp and it worked great. Big difference vs. w/o.Make sure you get a good one (at least $100)

Forum members will tell you they **** because they never used one

Told you

Ive used one and i'd spend the money upgrading my alt's and batteries anyday...it's so much more solid than trying to save yourself with capacitors..

ok, thanks for not trying to bs. if you have been telling the truth, then those were some excellent results using a cap. thats great in your install, but not everybody has as high of hopes for them as you do. most of the time, they do not increase/decrease performance at all. therefore they are not necessary. thats why your hearing them being called pointless, and a waste of money. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

oh, audiobahn is junk tho, and there is no doubting that //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I can honestly tell you a stinger or other good one does the job for 1000 watts.

The cheaper ones are trash. Even the guy at the shop told me the same thing and he was selling the cheap ones.

Anyways, yeah, Audiobahn is junk too imo, due to the fact that I blew that tweet quick in my one setup, although I may have been overpowering it a bit...

Real ngga sh!t tho, it sounded dam good for what it was (semi-budget system).

Wouldn't buy AB again tho

yea i like the guy who buys a cap and is like yay no more dimming, then next month he is buying a new alternator and battery because he electrical system wasnt up to par

Caps are good filters .....

There is a good reason why ALL of the SPL heavy hitters put them in the first year they became popular and took them all out by the next season. They do not have a big enough charge to do anything for big systems. Also if the ESR is more than like .01 ohms, they are similiarly useless.

4k watts you need...........1290 farads of caps.

To be successful......

.....in our testing....1290 farads and mmats amp...Voltage at 14.7 at full tilt drop 13.9 volts clamped 4300 watts @ .05 rise........turned voltage up and burp at 16 even and drop was 15.5 amp did 5200 but blew up cause too high voltage. Caps will only do you any good if you have like 1000 plus fards.......they discharge to quickly and then drag on the batterey the whole time trying to stay charged...

we used them in a comp vehicle we had 2580 farads of caps.....we set it up so that we charged them off a 16volt battery with a solenoid to shut the batt off from caps when they were charged....you want to burp directly off the caps only no battery, because while the caps are dischargin they are tryin to pull from the batt at the same time making them weaker and score was 1 db down. but disconnect battery and it gained a db just off caps.

but my point is you will need more than a one farad cap to make a difference.......and a battery is cheaper, makes a huge difference, more dependable.

and the caps we used were 430 farads a piece........Maxwell technologies

they are similiar to these ours are the 430 farad version

Ace Ventura... The problem is not anything with personal experiences.

It's the fact that it is scientifically proven to be a detriment. The capacitor is intended to help minimize voltage drops, and put less strain on the alternator. However, when the capacitor discharges, it puts additional strain, and more voltage drops, when the alternator is forced to charge both the cap and the battery simultaneously.

In lower power systems, this is less of a problem, as the alternator can keep up with charging the system, and the cap might assist in preventing slight dimming. However, if you are to the point of extreme dimming, then a cap will only hide the problem. It will eventually fry the alternator when it tries to keep up.
