i've always heard 1 farad for every thousand watts, but I'd go bigger...why not a second battery?

dont get a cap, do the big 3 and get a battery or two if you need it.

You don't need help with capacitors... You don't need capacitors... Take the advice already given.

If capacitators did absolutely nothing then they would not be produced. I am amazed at all the people that say they do nothing. That is not true indeed. While a capacitator can temporarily help with the electrical, it is merely only supposed to be used as a secondary option next to an upgraded alt and/or battery.

The reason you see caps in car audio is purely a marketing ploy I'm affraid to say. They do little to help an electrical system that good steady current flow from a stong battery, alt and wiring couldn't provide.

Its a good way for the resellers to make serious coin.

When I had the 1 woofer/amp combo and no cap, when the bass would hit my voltage and lights would drop like crazy and take a while to charge back up. After I got the cap, my lights would still dim and voltage would drop, but it would recharge almost instantly. I guess it just happened to be my lucky day huh?

I wouldn't say we make serious coin on caps, the mark-up is only about 25-30% which in retail is not very good. I sell them at my store to the people who don't want to spend the money on a bigger battery and thicker wiring.

youre right, they do SOMETHING, but it is neglible for what most people think they should be for, a lack of supply that should be remedied by an alt and/or batt.

I definitely agree with you on that 1. I laugh at people who try to run 1K plus watts off of their stock electrical system plus a CAP......

I would have taken the money invested in the cap and put it toward better wiring/electrical system. It would have resulted in no dimming and a steady current.

You were purchasing from the wrong supplier.

you could get a capacitor crazy cheap if you just find out all the specifications they sell audio ones for and just buy from one of the 3 big electrical supliers out there. its not an expensive part, its just companys puting there sticker around a general use capacitor and selling them in the audio market.

that was my feeling, but i couldnt find one elsewhere. i think it would be sans voltage readout as well?
