Well that's what I was getting at was that the cap wasn't going to help. I took what he said out of context really. I told him I probably wasn't going to buy a cap, which was when he said "dont blame me if you blow your shit because you don't have enough current".

yup
lack of current will kill things
the fallicy is that a capacitor is going to make any difference.

Which his statement is true also.

But his argument geared towards the cap being a problem solver is inacurate.

Lol kiki I love you, man...I'm gonna have to tell him to come register here so he can get flamerized.

I was arguing with him and he was like "Dont blame me if you blow your shit cuz you don't have enough current"

hey at least you didnt go from 14.4 idle to 12.6 idle LOL.

in simplest terms, the voltage of the capacitor follows the circuit voltage.
when voltage rails sag due to a lack of current, the capacitor will do the same, thus not providing any help in regards to voltage rails. A capacitor does have uses, mainly in reducing AC ripple, and reducing propogation delay, but they do nothing at all for the actual rail voltage or supply of current.

If your friend wants to argue about it, he's welcome to argue about it with myself, or Richard Clark, or really anyone with an extensive knowledge of electrical engineering who actually understands how a capacitor and electrical circuit works, but I suggest he come prepared, and have his reference material handy.

speaking of dimming lights...kiki would you direct me in the...direction of that topic about how cap's do nothing. I tried explaining this to a friend, and he argued with me. I figured I'd point him to it.

the 'big three' myth doesn't do anything for you if the car is newer or in good shape with a stock electrical system.
on oldercars it helps because often the stock wiring is corroded and worn, and thus unable to carry the current it should.
Stock systems use cable sufficient to handle the peak output of the stock alternator, and your audio system isn't going to be able to draw any more current than the car can provide via that alternator and battery.
If you upgrade the alternator and battery, then sure, you'll need to upgrade wiring to compensate for the increased current capacity of the system.

Anyone who tells you to just upgrade the "big three" and it'll fix all of your problems, is seriously misguided and just passing along their misinformation to you.

If your lights are dimming while you're driving the car, you need a larger alternator, less volume, or a smaller audio system. Only one or a combination of those three things is going to help you with your problem.

Changing the wiring wont give you more of anything. It just makes it easier for the current to flow. Thats the bottom line.

Your loss of .2 volts is minimal. It may be due to a crimp connection, bad solder joint or as others have listed above.

With a 50 amp maximum draw and an 80 amp alt its just not big enough.
