ok ive always wondered what is the voltage adjustment on my cap for and what should it be set at

If youre entering SPL comps...ditch the freaking cap!!!!! It's probably hurting your score.

eh its kinda a PITA to remove them though, ill have to give it a try though

depends on your amp, generaly about 14.1V

If you would have read his post earlier about entering in USACI you'd understand. And if you even for a minute understood car audio SPL competition you'd again understand. So check yourself fool.

Grimor, what a cap does, and how it does it WILL hurt you doing straight out SPL comps, its a fact, why you getting all bent about something that obviously u dont understand to begin with?!
On the other hand....you have other fingers.
I just bought a 20 inch widescreen ultrasharp flat pannel..I'm going to have to subscribe to the high quality porn places now......damn
well i am a real audio newb, anyone care to explain why it hurts it?

stfu, I do understand audio spl comps, and if properly wired a cap won't hurt you.

a capacitor is used to even out the voltage flow, when the bass hits really hard lights dim cause the voltage drops the cap acts as a fast discharging source of power to assist, however it has to pull power from the battery in order to charge back up and thats where it hurts the SPL, most spl cars are only good for one "burp" and then the battery needs recharged
Im still not understanding what this voltage adjustment is for though which was the reason for the post

A capacitor is also used for a more rapid discharge of power faster than the battery can respond to. When used properly it can help in SPL comps. Like you said, it's one hit and the system is dead, you want the capacity to discharge a large amount of power in a very short period of time.

the capacitor is not an alternator, it is not a battery, and it is not an amp, it will not INCREASE the power for that burp, it will only discharge when the power is lacking... in a one burp situation, it would be useless, when used longer than that, it will actualy hurt you, because your system is going to be sucking power, then the cap dischrges when theres alull,... but then that lull lasts, and instead of all the power going to the sub, the cap sucks some of it up to recharge... its not a long process, but its long enough to bother.

K...thats all I need to know about you and SPL comps. I'll have to remind myself never to read anything you post in the CA forum from here on out. And if you tell me to stfu one more time I'll pimp slap you through my screen.
I have no idea what the voltage adjustment is for. Maybe it's just there incase you happen to be running an elec. system that puts out more than 14 volts...say 16v (like you have to reduce it to 14).
Anyway...sell it and buy another/ or a better battery. You'll benifit MUCH more.

back on topic, i woudl like to knwo the answer too.....

@!#$ you, maybe if you actualy knew anything about electical systems and what a cap actualy does you could buy a clue. stfu and come get some.

You're right...please explain how a cap and a cars electrical system woks.
RE Audio
Grimer is dead wrong. Grimer go buy a clue. Lash is correct. After that cap discharges it does need to charge back up. The cap is not going to charge itself, where do ou think it is going to get the power from. One guess now! Oh yeah, that's right, the frickin battery. Which in turn is going to supply less power to the rest of your system due to the cap recharging. Like it was said before, this process will not take long, but long enough to notice. So in other words Grimer why don't you stfu and learn what you are trying to talk about.
ok, ive been silent on this for long enough. Do any of you even know why people use a cap on an audio system? Its for a smooth dc output out of your electrical system. As your alternator puts out pulsating dc, from the converson of AC that the alternator produces and sends it thorugh the rectifier, this pulsating dc is fed to the battery and out to many parts of the car, that don't care if its pulsating dc....but a high power amp does care. so you need a capacitor to smooth this dc power into smooth dc.....google "filter capacitor" and you will understand. the cap just provides smooth dc to the amp, and will send a smooth dc voltage and current signal to the amp allowing it to drive your subwoofer more efficeintly.
the reason a cap will stop your lights from dimming is because it helps stabalize the dc system which reduces the internal resistance of the battery plates which lets it put out a more stable current and voltage output.
so basicallly a cap serves a good purpose. now....... can a spare batt serve the sme purpose.....yes, is it cost effective......no.
I'd suggest taking some college level courses on advanced electricity before trying to act smart when it comes to electronics theory

Amplifiers already have circuitry to filter out the small ripples. They don't need external filters.
Caps can help with dimming and with sq. Their not going to help with spl.
I'm undecided on the question of if they can hurt spl setups.
Rodimus, I don't know what the adjustment on your cap is for. If it's just a cap, then there's no way to adjust the voltage level (a capacitors voltage is completely dependant upon the supply voltage). Could it set the trigger level for some sort of alarm?
you may be right labotomi, i don't have an amplifier here to look at, but either way, my point was that im confident that a capacitor can't hurt a stereo system, only help it

You can't teach an old dog new tricks, but you can kick the @!#$ out of it till it listens.
These Cap threads always end up the same, everyone thinks they are right because of all the crap they read on the internet instead of actualy learning something for themself. A capacitor will not detract from your electrical system in any way shape or form if properly installed. Read a book and learn for yourself.

A cap is used to clean up the dc signal. Matt's capacitor has voltage adjustment for different systems. Some people run 16, even 18 volt systems. More voltages = more power. Some amps can take it, some can't.
Ever try burping with a cap? The cap is constantly going to try to recharge itself and become useless in a very short amount of time. Actually, with it trying to recharge itself, it will drop your voltage. Wysiwig, Sndsgood, n8ball2013, Lash, etc... all run pretty big stereo systems, me included, and don't run a capacitor. Team Gates' Bronco, the loudest metered vehicle in the world, does not run capacitors. Ask any of the other big competing SPL teams, they don't run capacitors either.
