I didn't mean to say that I condone the use or purchase of a Cap.  I did mean however to say that they do what they say they are supposed to, and thats keep your headlights from dimming.

And yes, if you keep a constant bass tone that is loud enough to overpower the alt and battery, yes the lights will then start to dim again, but seriously, who has a system that can do that?

My system was only able to draw enough power to dimm the lights for short periods of time, any constant tones would have no affect.  So in my case, the cap was perfect.  No need to install a 2nd battery, bigger alt, etc, unless you really need it.

You're right, in most cases, a bigger alternator, or battery is not necessary...  I had over 1,800RMS watts in my last car, and I had the stock alternator... the wiring is seriously the biggest deal... go with at least something as thick as a wine bottle cork...

my lights used to dim, but I upgraded from 4AWG to 0/1 and it all went away...  I only upgraded to a Yellowtop later, because I killed my stock battery (it was the original delco so it was going to die anyways.)

Most people believe that a Cap is the answer to all their problems, but they fail to realize that what they are doing is actually adding another load on an already strained electrical system.

Here is a great article written by one of our mods at Car Audio Central, it really breaks down what a cap can and cannot do.

Oh man, I just realized this thread is old!! Oh well, I'll go ahead and post it since the info could be useful to someone else.
