Installing Capacitor, need help.

[yacob.naif 10+ year member]

i forgot to mention, the reason this is important, is because your alternator only creates the amount of current that is being demanded at the time, so when you have rapid fluctuations in ampere draw, your voltage will drop momentarily while it adjusts.

These tiny, short, voltage drops will happen in a car no matter how big of an alternator they have. An alternator never makes 'extra' energy. It makes enough to charge the battery, and power your accessories, and that's it. So when the demnd suddenly increases, your voltage drops.

The capacitor eliminates these short voltage drops by constantly showing your alternator a constant draw, and eliminating these short gaps of current when the alternator has to readjust for differentials in the ampere draw.

brents, i understand that you corrected yourself. but my prior comment was based on your initial misinformative post:

Yeah, do the big 3. Caps really are good for bling. People may argue that, but the cap is good for one thing

I don't believe this is accurate...but I don't know for sure. The only way to test is to provide a load.

read the alternator sticky. "Will a High Output Alternator Fry my car's Electrical System"

it's in the 6th mini paragraph.

"

Nothing in your car will be stressed. It is the nature of a generator (alternator) to only supply enough current as is needed, so usually it's just trickle charging the batteries and up keeping the car's electronics.... This is the case for a stock honda 40amp alt or a 350ampre big case custom alternator."

Hey, thats cool, I misled, I just get a little wound when my knowledge is questioned, and when people ask about caps. i had one with my first system, and it made no difference in output, or elec. drain. I will try to dig up my documentation of it. I dunno if I still have it though, that was like 8 yrs ago.

it's cool, i wasn't trying to start trouble.

I read the sticky. i didn't know that.

Where the hell did you copy and paste that shit from, I KNOW you did not write that on your own... You are far to stupid to do so.

Anyway, read what I said ****face. They do not work properly for eliminating voltage drops, they are not a source of power, they can only store small amounts of power and the recharge rates are not enough to help any major amount.

the new 10,000w rockford amp draws 300A of power.

How? Capacitors.

I would consider 10,000w a MAJOR amount.

i don't think there's a better example than that.

and what's with all this hostility? i don't recall attacking you in any way... if i somehow offended you, i wasn't trying to ruin your day, i assure you.

oh, and to the OP. if you have a large class AB amplifier, you may find that dimming persists even at moderate volume. such amplifiers have an efficiency that changes with volume. as volume goes up, so does output power and efficiency, but as volume goes down, efficiency goes down. the net power draw doens't go down near as much as it should.

$200 cap?!?
there's 50 and 100 farad caps on ebay for that.....

and for half of that, you could do your big 3, and rewire your entire install in 1/0 ga.

caps DO serve a purpose, but there's no way you need one for that kind of power

i wouldnt have bought it for $200, i saw it for 50 on etronics, which is cheaper than a battery

but i understand it all now, so thanks

Big 3 can be done for ~$10.00, and will be more advantagous (sp) than a cap, even in the bling nature. Whats better than popping a hood and seeing properly ran wire under there? Well, ok, a nice small block or big block would definitely rush the blood a little faster to my friend, but the end result is the same.
