how much is too much

[crazydude133 10+ year member]

please explain how a battery can help with ---------any -------load when the car is running?

just think about this,,, the battery is what holds a constant amount of power so that when you use things such as any radio, heater, etc. so that when you for instance kick your heater and radio on at the same time you car wont just stall right out. The battery is very important because it smooths out most of the varriations in the amount of electricity your alternator can create. if a person gets a better alternator and a better battery then when they hit the heavy bass notes the lights will only dim just a hair or not at all. a better alternator is a VERY good way to solve lack of power for a stereo. think about it,, you can throw all the caps in there that you want but the fact is your alternator will still be making just as much power as before. a cap doesnt make any power, it will just level out the lack of power by storing power when heavy bass notes are not being played. A cap is also great cause amps like to recieve a more steady flow of power. so yah all of those are great but the most important is the alt and battery

correct--- it just help with loads that EXCEED the alt ability----to do so the voltage must drop 2v to the open circuit voltage of the battery

The battery is very important because it smooths out most of the varriations in the amount of electricity your alternator can create.

no ---- you had it right before---just helps with load exceeding the alternator

if a person gets a better alternator and a better battery then when they hit the heavy bass notes the lights will only dim just a hair or not at all.

that really depends on the alternator and the reason WHY the lights are dimming[--- batteries don't help with dimming ---read above as to why.

a better alternator is a VERY good way to solve lack of power for a stereo.

depends on what you mean by "lack of power" a 100A alt can run a couple 1000 watt amp fine with a cap

think about it,, you can throw all the caps in there that you want but the fact is your alternator will still be making just as much power as before. a cap doesnt make any power, it will just level out the lack of power by storing power when heavy bass notes are not being played.

correct--- now think what that does for the alternator--- causes you NOT to need a bigger one

A cap is also great cause amps like to recieve a more steady flow of power. so yah all of those are great but the most important is the alt and battery

you can just forget about the battery ---- you really don't want to tap into its power or it going to leave LESS headroom for the alt to run the system. All power should come from the alt NOT both or you will run into really bad problems

How is getting and HO alternator($$$$) & and a new battery($$$$$) more cost effective then some cheap capacitance?

Are you saying that a HO alternator is gonna cost much more than 3 caps? And since he only needs one cap: getting his alternator rewound would be about the same cost(maybe cheaper) then buying a single cap. he's not going to need 250 amps from his alt to push a 1000 watt amp. He'll probably want 130-140(remember the alternator needs enough left over amps to run the rest of his electrical system)

Did you realize that a battery takes ALL the load when the car is running? the only difference is that the alternator recharges it. if you don't believe me then go try and run your car without a battery in it

Originally posted by chris229 correct--- now think what that does for the alternator--- causes you NOT to need a bigger

incorrect. if you knew anything about caps then you would know that they only help during long/loud bass hits. not to mention they only help for the first .5-1 second of the bass hit until the alt catches up. now what about the rest of his music?

you wouldn't even need that much with a cap

read your post and go put a volt meter on your car when it's runing. Bet it says more than 12.8v-------- tell me how current is going to flow from ANY battery when its voltage sits below the alternator------I think you've mistaken me with a guy who doesn't know what he taking about----the alternator takes all the load ---------if you don't understand that then ---- I don't know what to say---- ALL batteries are loads on the alternator---------- they pull 10-15A fully charged ----- a slightly discharged one @ underhood temps can pull 60A+

I'm not sure if you know or not but amps don't draw current like toasters or ovens-----------they are HIGH SPEED switching some in excess of 100,000hz --------- cap recharge at a speed FASTER than that... ------- but I guess i don't know anything

Hey jack ***! Try starting up your car and taking the battery out once it is already been started.......Just disconnect the ground and see how well the car runs...... Oh yeah it will keep running. Because the alternator is keeping the load!

Chris! Since when was it ok to battle wits with someone that had none? Or was it you that did not know anything? LOL I think this one needs a step back and walk away........clueless sometimes is closed minded as well because they have been told too much misinformation. Winning the battle is one thing.......playing with your food is another LMAO. Take it easy bro

alot of people say that to me---------I'm not around to battle with anyone and say ------I won. I'm just tring to get through to people. which sometimes may read like a battle. That way --- next time THEY hear someone stating the same misinformation they can correct them too. If you just let it go on an on an on without correction they will believe it -----just like you see all the time.... I'm just tring to spark a person to think for themselves an not just pass on misinformation. when a sales guy tells you that a battery will help with the load-----simply ask how---the laws of physics totally oppose it

I don't think i'm smarter than anyone i've every met or smarter than anyone on this board----------------I just read alot more tech books most likely

Note: I never said you were more intelligent etc.... I was trying to make light of it because it seemed as tho you wwere almost getting frustrated with the whole ordeal. I can not agree with you more on you rconcepts and know the whole deal about the tech books etc.... I have an advanced degree in electronics but at some point it just seems to get frustrating trying to get thru some BASIC principles.

Could you explain how I am a jackass please? OK so i was wrong about the battery taking the load. i just used my common sense b/c the alternator goes thru the battery and i know that the alternator recharges the battery. this argument has taken so many turns so im going to go back to the original question. three caps is a total waste of money for this guy. And really, we would need more information to determine whether or not a cap or a alt upgrade would be more suitable for him. However I am going to GUESS and say the either a cap or an alt upgrade would work either way

we do need more info------ it's just one amp though--- the amount of capacitance is tied to the amount of power the amp puts out. You are correct no one can really make any recommendations until more is known

well thats all i have to say about that
