Im going to have to disagree, ive hooked up caps and thought there wasnt a difference. Then for one odd reason or another my system wasnt as loud as it was. Turns out the cap came disconnected. Hooked it back up and it was loud again.

I wont say they are worthless, but they arent worth what you pay for a brand name one.

A while back i went and upgraded to a yellow top and didnt hear a difference. However when i went from a 110 amp alt. to a 200 i noticed a world of difference. When i added the isolator and 2 more yellows it got even better.

To sum it up dont waste your money on the small solutions just buy the alternator.

yeah but I can't afford to have a cap that just looks good. Were would I find alt's???? My car will be a 91 Buick Century. It has a 100 amp alt and I was told that it would be sufficent. Would it... being pun off a JBL BP1200??? How much of an upgrade wouild I need and how much would it cost???? I don't know were to look ot get a new atl upgrade. the best one i found was a 105 amp for $200. No since wasting the money for 5 amps...

Any help would be appreceated

THE WHOLE THING!!!
Hmm, i have a 90 amp alt and a hifonics bx1500d and only have a little dimming while the system is running and the headlights are on. Other than that it's fine most of the time. I'd put the system all together first, then see if you even need a new alternator.

Don't bother with the cap.

Fair enough, this guy wanted someones advise, and this guys saying there worthless, well back it up with your personal experience or a "supposed article" still waiting on that by the way. i would never buy another one again but saying they are worthless and not backing it up, thats ignorant.

They arent worth what you pay for them.

Kickerlivinloud, i hope that bickering aside your question was answered.

It makes perfectly good sense if you consider the law of conservation of energy.

If in one case your charging system is powering the car's electronics and the stereo system -

And in another case it's the car, the stereo, and charging a cap - the voltage is going to decrease - it HAS to - maybe only slightly, but it does.

Another thing I found interesting is this:

One note I might add is that this was a two thousand watt system driven right to clipping and the average voltage stayed above 12.8 with a stock 80 amp alternator.Under these conditions the battery would never discharge!
