Hey bugs, thanks for the info. You make it pretty easy to understand. I have had the system up and running for about 2 weeks. If I got it right the cap should be charged by now right?? I don't play my system LOUD all the time. I have seen the voltage displays on one of my friends cap in his system. I understand what you mean by going up and down. When the really powerful notes hit the voltage dropped, and when the demand lessened it went back up.

I really appreciate the help.

And yes it could be a very long debate on the pros and cons. Myself I like them, but that is merely my opinion.

Thanks again,

Tim

Oh yes, if it'* working, it is definitely charged. It should literally take seconds (or less) to charge a cap.

And yes, you have exactly the right idea, the idea of putting a cap in a car audio system is to support the current load for those loud "thumps" pumping through your amp to those subs. And regardless of the debate, it can't hurt anything. Electrically, if it does anything at all, it will help. I've seen people use a second battery, which is used along the same lines for the same reasons. I'm sure there'* people out there who use both a second battery *and* a capacitor. Again, it can't hurt. -But consider getting a high current alternator to keep things from discharging and leaving you stranded. (That really does happen.)

I agree completely, one of my friends has a JL 1000/1 and a 13w7. He put a cap and a second battery. But did nothing else. I thought it would have been better to upgrade the alternator than the extra battery.

All the extra battery did was increase his engine off listening time. I think people have the wrong idea, they think extra battery means extra power, and to an extent it does. But the extra power they provide also means an extra load on the stock alternator that is already working overtime to provide power to the accersories and the stereo system. I know a cap is not a cure all but in the right situation it will help.

If you are gonna be running that kind of power I think you should just do yourself a favor and upgrade the alternator.

Anywho my 10 cents,

Tim

A capacitor acts like a second voltage supply in parallel with the battery. As you guys stated, when the bass hits the cap picks up the voltage where the battery leaves off. A cap smooths out the resultant voltage supply and will reduce ripple which can cause distortion. Also, a cap can provide current much faster than a battery can, therefore reducing the immediate strain on the battery. But of course, a constant bass note drawing too much power will drain the cap and then your actually worse off because your battery has to run the system and charge the cap. People often use caps to patch a weak electrical system. A better alternator would not hurt, but keep in mind that it will take more power to run a more powerful alt.

I've always wondered what the HP hit is between the stock alt and the high-output aftermarket alts.

Time to supercharge?

Neglectable unless you spend your life on the dyno and measure tenths.

That'* what I figured! I mean, you can feel the power loss when you turn on a car'* AC. But I've never heard of anyone complaining about their loss of power after upgrading to a high output alternator. -Which is just another reason why I think a high output alternator is the first upgrade one should implement with a high powered audio system; before adding capacitors and extra car batteries.

Thx for the info!
