ok,
this is kinda another stupid question, but i just want to know if anyone has actually tried it yet...
can caps help you out on an SPL system? I know they help a lot on the daily driver systems by regulating the voltages so that the rest of the electrical system in the car is not affected by the stereo and they can add a little punch to "average" systems.
but i figure that in an SPL system, not having enough capacitance would only be impeding your voltage and current from the battery. right now, some of the bigger caps are about 5F big - would this be enough to power a system running a couple thousand watts?
in an ideal case, if the cap could handle the voltage and current without hindering it, it would create a more stable, uninterrupted singal and therefore give better power and spl. but i'm not sure if there are any caps on the market that can produce this...

For the most part A cap will Hinder SPL

Hinder.

Good battery and you're good to go.

thet're kinda useful as a bandiad for everyday, But when you wanna pound it loud, take it out.

if i could find a couple more 1 farad for cheap i'd buy them they are useful in home with a battery charger to run an amp

Im taking mine out of my car, it fixes nothing haha, I just kept it in there because ive been using it as a distro block.

I never thought of using it for that... I just might keep it now lol.

yeah capacitors actually experiance a voltage drop across the terminals...usually of a few tenths of a volt. this actually makes the amp put out less power and so it hinders the SPL score. I remember back in the day MA Audio used to have an extreme vehicle in Canada with a row of capacitors on the side. all of them had digital readouts and you could see the voltage dropping as you went down the row of caps lol

i kinda figured that much about caps...
but does anyone have any idea about how much capacitance (in farads) you would need to run a few thousand watts uninterrupted?
i'm just curious b/c in street a/b you're only allowed 1 cap and i wanted to know if they make one single cap big enough to accomodate a street competition system....

1 Farad of capacitance, not one cap. those 50-100 farad mega caps are no bueno.
