capacitor help!!! - General

heeeey so i have one ten inch sub woofer and a 750 watt amp running off my car battery. it seems to work just fine, but i recently bought a 4pc ledglow interior lighting kit, im worried that this ammount of power drain will largely affect my battery and/or alternator, so i started looking at capacitors but i have no idea the ammount of farads i would need, can someone please gimme some suggestions or advice on how farads work and wether id even need a capacitor, also some preferred capacitors would be helpful

I seriously doubt LEDs, quite possibly the lowest power using devices ever made, are going to affect the overall power draw of your system. Unless of course, you're running your car with a pack of 6 AA batteries.

Aren't capacitor only useful when you've got a 1000w Subwoofer and a good overall audio system, enough that you notice loss of tensions when using them at higher than casual volumes? (Correct me if I am wrong or lack stuff about this subject) If I recall it's 1 farad for 1000w. But then again, as you said, you added LED's to your car, on LED's a battery will last a fucklong time.

Capacitors are for teenagers who wear straight brim hats to make their 4000watt (max.... 400watt rms...) Audiobahn system with dem chrome sub baskets sound even more awesome when they describe it to others. The theory behind them is to store extra power that can be dumped quickly into the system when the system demands outweigh the ability of the alternator to supply that demand and also maintain charging voltage. When the bass hits hard the system pulls more than the alt can supply in that instant and the headlights dim... the cap is supposed to alleviate that by keeping the voltage levels high enough. The flaw in that thinking is that the cap takes (IIRC) something like 4 times longer to build charge that it takes to dump that into the system... .. In the end really all a cap is is a bandaid that sometimes may possibly maybe help with headlight dimming issues while the system is beating down the block. Correct ways to deal with headlight dimming issues: -upgrade the 3 primary large gauge cables in the vehicle's charging system. (never a bad idea.. and cheap, too) -higher output alternator The draw an underbody kit pulls is negligible to any charging system, really.. 5 amps maybe? It's nothing, don't worry about it.
