    A capacitor will only help somewhat. I added a capacitor to my car and it helped a little bit, but the best solution is to get a higher output alternator and a better battery. Also, make sure you have large diameter (low gauge) power wire, especially from alternator to battery, battery to ground, and battery to amp.
    How many watts are you running?

    the stock alt/bat should be suffiencient. I'm running a car pc and 2 1000W mono amps... I did have the headlight dimmage, but after a cap its fine.

    I agree with this.


    But more to the point, it depends on how much power that you want to add. If you are staying below 300W then you proabably don't need to do anything(well other than good wiring anyway). If you are approaching 1000W then a cap is gonna be a good idea. All the stuff that Franz was talking about is a good idea too.

    A slightly smaller pulley on the alternator would effectively increase the RPMs and keep its output up a bit at idle speeds. But this may very slightly decrease you MTBCF for the alternator if you high rev regularaly. Probably won't be noticable though.

    Please note: no cats were harmed in any way during the making of this post. But there is always later.

    I believe the capacitor is only to filter out spikes and keep a steady flow of electric to the system, but doesn't do anything for power for the rest of the car.
    If your system is really that LOUD that it will bog down your electrical current. Then you should look at a bigger battery, or a bigger alternator.
