I wil tell you this though:

There are a lot more powerful carpc audio setups here (mine is one) that do not have your issues and a capacitor is not required. It sounds as if you have a power supply or wiring issue somewhere.

Have you done the "big three" yet? This will fix most power problems in a "modest" system such as yours. Alot of wilder systems also.

2k is right and you've been listening to the wrong people................

Nothing personal.

Good luck

im only determined to fix this, hence me out there today in the 96 degree weather disconnecting my cap to test the theory. it didnt pan out and i posted my finding. seems perfectly reasonable/logical to me.

as for the big three, im doing that next, i just read about it and never really heard of it before today, while i dont think it will fix it because my life is never that simple, i will give it ago, and once again post my finding either way.

The "big three" has fixed more light dimming and power issues than you might think.
It's quick easy cheap and simple.

Actually, it should be the first step everyone does...............

Even on a stock vehicle.

Good luck.

WOW WOW WOW WOW!!!!!!!!!!!!!!! thats all i can say.

I cant belive I have never heard of this upgrade before, its so simple and makes so much sense when you think about it. This made all the difference in the world. It got rid of the rebooting and light dimming completely. I ran 4 guage on all three wires on top of the factory wiring and it solved my problems like magic.

That is with the cap removed. so i guess caps are useless wastes of money, cant belive so many people are wrong, but then again, look at religion.

When i changed form 8 guage to 4 guage back in the day it made a huge difference, and being that the altanator is running on like 8 or 10 guage, and the amp is trying to pull tons of power off the 4 guage it just creates a big bottle neck, run the 4 guage all the way to the alt and then your set.

I actually went to installations unlimited today to buy the wire and asked the guy if hes herd of the big three, he hadn't so i explained what it was, he said they only do that when somone upgrades they re altanator.....thats pretty ******* stupid.

They are like the big car audio install guys around here, and they charge alot, and they don't do that service religiously? thats amazing to me.

Thanks for the advice guys, it really made a difference for me. i suggest anyone else reading this to do the same if you havn't already, its no joke.

THIS SHOULD REALLY BE MORE WELL KNOWN!!!

And no, a capacitor is useless. And yes, a capacitor is more trouble than it is worth. Just bypass and see if it works. And if your lights are dimming then you have some issues you need to correct. A cap will "bandaid" it, but as you are finding out not well.

Also a cap has a maximum current it can pass through. So if you are using awg to the cap and then to your components from that, you may be underpowering them because the cap is the chokehold. Once the capacitor is called on to give up its storage of energy, the current available drops exponentially and will take some time to "recharge" by Kirchoff's Laws. So if your battery cant handle it to begin with (which is why the cap is used), then now it has to both recharge the cap and power everything

why after bashing the cap did you make no mention of the big three as a possible fix???

seems if your gonna say something is horirbly wrong, you might mention an alternative solution.

one thing you are probably going to want to do is after this is upgrade your alternator. dont just wait until it kills itself along with your battery, have it re-spun or replaced with a higher amp output version. your stock alt will probably not last very long with a system in it...

glad to help.

As I've always said, the components are only part of the equation. The install is what makes or breaks it.

Cheers

Because by the time I read your thread again, it had already been mentioned. Seemed sort of useless to say it again.

But I can if you want... "Why dont you try the Big 3?". I think this is even mentioned in a FAQ somewhere.

Good thing you got it working, and now you can "preach" (

) the uselessness of caps as well.

its lasted 2 years so far, and if it goes, then ill get the higher output one, if it takes my battery too.,....so be it.

A higher output amp is not really required on most stock to mild systems. It is nice to have a higher amp alt if you do a fair bit of traffic driving though. Not because it has a higher peak output, but because it produces more power at lower rpms.

And if the alt dies after "the big 3", it will be because it's on the way out anyways, not because of the improvement in the wiring.

But a bad alt will take out a battery. However, it doesn't "kill" the battery, it lets it die. The battery stays in a state of discharge as the alt can't bring it back to full charge, the plates sulfate, and the battery dies a slow and painful death.

Batteries need to be kept in a state of full, or near full, charge to get the full service life out of them.

Cheers

so what you're saying is that "The Big 3" upgrade will negate a need for a new alt or re-spun alt with a powerful sound system? did i catch that right?
