A cap is useless, it can hold a charge for what??6-8 seconds?

Lame.

umm, and i'll state again that a cap discharges its juice quicker than a battery.
It pulls it's power from the alternator and battery, your re-routing where your power comes from for mere fractions of a second, if theirs any performance gained at all it's very very minimal.

Add a battery
Upgrade your battery
Or upgrade your alternator

Regardless of how cheap it was, it was a waste of money, plus they can be blown very easily. And 99% of the time the lights or digital read-out on them stay working, hell mine was blown for maybe months before I put it on a meter and relized it was doing nothing but lighting up. And with that going on I didn't notice a single difference in "my lights diming" it still did it the same amount.

If you are still wanting to hook it up after reading all of these.
Always hook up your ground first and last when you un-connect it. The only real thing I think you need to do specially, is when you take it out disconnect your + and let it sit for 15 minutes or so then take the whole thing out.

Thats just my personal way, seeing is how mine blew up because i "took it out too fast" and popped a $200 cap, that went right down the drain. Never buy another one.

Anyway good luck!

alright, well even if it is useless i bought it and am going to use it. I charged it with the resistor. Then when i hooked it up it blew my fuse by the battery. I just put a screwdriver there to see if it would work and it did. Did it just blow the fuse because i did not charge it enough?

you guys are retarded. if they didnt work do you think major competitors would spend the time and money and waste the space of installing these? seriously - you guys - retarded

I have a cap for a few years now. I didn't notice that much of difference the yrs I have had it. I transferred it to another car and didn't know if you touch together the - and + together you would see sparks. And it was alreadydisconnected fromthe battery power. The damn thing stored some juice in it and it nearly made me crap my pants.

They are of low value and only useful under certian circumstances.o
Once you've upgraded your charging system if you still experience voltage drops the fast response of a cap can help to smooth them out; as long as the charging system can support the extra load of the cap being placed on it.

When they're thrown into the mix on a weak charging system, they may mask the drop problems, and help keep headlights from dimming; but in the big picture they're actually causing more stress on the charging system because they must be continualy recharged taking away from juice that could be provided straight to the amplifier.

Enough?

that makes no sense. take your butt down to daytona for the spring break nationals. walk around and look at private individuals that compete on a national level (obviously spending serious dough on what they are doing) you'll notice they use capacitors.

Yes, but your car is not a competive car, and you do not have any contracts that state you must use all of a companies propducts.

77stang,

Caps are a storage medium for a current. When you let that half a millisecond charge of power out, your battery and alt must work harder to provide your system with power. A cap is nothing more then two parrallel plates and some sort of fluid inbetween. The plate on the battery side must be full of electrons before they bounce to the other side. It is quite simple to say that a cap actually creates more of a drain on achargin systemgiven that most people play more then a millisecond burp. If you have a cap you might think itlowers the strain on your system becuase the headlights don't dim anymore, but all you are doing is transfereing the strain to another component.
