ok then why do we put out voltmeters on DC to read voltage when the car is running, since the alternator puts out "AC"

Again, capacitors are good for storing voltage but just like amplifiers, most of the accesories in a car are current driven so how is it going to help?

Stinger recommends 1 farad per 1000 watts if its electrolytic,if its a hybrid then its doubled.I personally think that excessive.I have a 10 farad in my FJ with 3300 wats, only bcause i had it laying around.

The only way it helps is by not taxing a alternator or battery.The less stress you put on a those two components, the longer they will last.The more stable current going to the amp, the amp will heat up less.This is nothing you probably dont already know, just a diffent angle maybe.

Well the battery can't use alternating current so the alternator output is fed into what are called diodes, which convert the AC into DC.

i tapped for the LOCs right behind the deck, less that a foot of wire between and used some 9 foot RCAs, and caps installed properly actualy DO work. the speakers that went out were the 2 rear subs and the 2 lower door speakers.

There 2 types of caps.Carbon alloy and electrolytic.Carbon alloy capacitors are more like a fast discharge battery than a capacitor. The farads ratings are determined by how long it takes to discharge the unit with a set load. The internal resistance of a carbon alloy type is higher than a normal electrolytic capacitor. This means that the electrolytic capacitor can charge and discharge much quicker than a carbon alloy type. If your system needs a battery the carbon alloy may be an option for you. If you just need a boost for musical peaks, a normal Stinger type capacitor will be better. Just an example, the internal resistance of an Alumapro CAP is 26 ohms; a common electrolytic capacitor is 0.00001 ohms. A Stinger Power2 battery is 31 ohms. If you measured the Stinger battery, it would be about 2000 farads. Get the picture???? Unless you plan on upgrading the battery or alternator, a cap is option.

i use the electrolytic capacitors not as band aids, but as extra add ons, ive already upgraded the battery and alt, but a properly installed CAP like u said cleans up the system and makes it easier for the amp to get the power for a big bass line. its easier to draw power from a foot of wire vs 15 foot of power wire.

i've goten it all hooked in and mounted and set up now, sounds so much better than before. mainly because i have all my speakers again used the LOCs right behind the deck then 2 9 foot wires to go to amp, mounted the amp on the passenger side floor board, up against the trans tunnel. ran good speaker wires to all the speakers and used insulated connectors attached to the factory speaker connectors to make for easy removal if required. ill snap some pics tomorow.
