I was referring to the 14.4->12.6 voltage drop and you're talking about 12.6->??? voltage drop.A stock alternator is not going to be able to supply 2kwrms you will need a battery lol to suggest otherwise is madness. Batteries are a drain on the alternator, batteries lose power when it is being used to supply it to your amplifier or other electrical needs of your vehicle. Batteries can only hold so much power the alternator is seeing them as a load yes to supply voltage to and you may loose a few amps....but you will gain amps that are available for your amplifier especially when the draw from your amplifier exceeds the ability of your alternator, which in this particular situation, it will.
Also not once did I say capacitors are worthless in general...just for his application with the amount of current being drawn from the amplifier and the amount of capacitors needed to keep the voltage in balance during the times when his system will actually need it are extremely impractical.
so what you're saying, is that the majority of light dim you see, is from around 12.5-13 volts? (which is the resting voltage on most batts).... if so, that is the DUMBEST thing i've ever heard... you realize that the majority of vehicles will sit at around 12.5-13 when ideling, right... the big problem you run into with dimming, is when you dip into the 11's... and that is the point at which batteries are helpful. yes, mis matching your batteries and alt (like say running 4 or 5 100 ah batts off a 120 amp alt) can run into problems, but no one is suggesting that here.I was referring to the 14.4->12.6 voltage drop and you're talking about 12.6->??? voltage drop.
A lot of people complain about dimming lights and think a fancy battery will work some voodoo to fix that when it doesn't. You're still going to drop from 14v to whatever voltage the battery is and you're lights will dim when that happens.
If you're having a voltage drop that's asinine, such as drawing so much current the car shuts off, then ya - you need an extra battery and/or more of them. This is a much bigger problem than seeing your map lights dim to the bass line.
idk i think successful troll is successfulAround what wattage should I consider using a capacitor? In the very near future I am planning on purchasing a 2400w amp(1200rms) and I'm just wondering if I am going to need a capacitor or not.
its a pretty old thread bro... check the date on the OPidk i think successful troll is successful
Capacitors are worth it in most cars; especially if you use old school amps.And yes, i will say it, capacitors are COMPLETELY worthless in 99% of installs... and are never practical for voltage drop.
I think you need to see my earlier post...Capacitors are worth it in most cars; especially if you use old school amps.
Ever hit the power window button and notice your lights dim briefly? A cap fixes issues like that b/c while an alternator or battery will be able to supply the current requirements, they cannot do it nearly as quickly as a capacitor. Furthermore, some amps (like the old school ones) do not like dirty power and a cap will act like a noise filter. But the best reason to use a cap is to smooth out the power going into the power supply. Those tiny bursts in the bassline is where a cap will help any system.
If you're SPL'ing your way to work or listen to music with long drawn-out bass notes; a cap will make no difference. If you're voltage drops to
There's a lot of mis-information on how caps work and what problems they solve. They're not miracle makers and will not give fulfill the promises made by commissioned salesmen. But they do have a use and purpose for many systems both big and small. Want proof? Search over @ DIYMA.
A good read: Capacitor Info
yes, a cap is useful for a "dirty" power supply... but thats about it... it will not help in anyway with voltage drop. you can spin it anyway you want... unless you are running a batcap, or a whole deck of caps, a single one will not supply enough current to assist in voltage drop.Capacitors are worth it in most cars; especially if you use old school amps.

Batteries are slow to discharge and slow to charge. It's why the lights may dim when you roll up your power window.and you say that batteries and alts cannot supply energy fast enough? i'm sorry, but did the speed of electricity change in the last few hours??? i'm sorry bro, but your arguments on this are completely wrong.
