if you are determined to run a cap...have it as close to the AMP as possible. (1 ft would be good)

it can help to filter the AC-ripple from the alt.

BTW...i have never seen someone put a cap under the hood...lol.

don't get a cap unless you have a ho alt. and most people say 6inches is optimum distance from the amps, no more than a foot. you want it as close to the amps as possible to deliver the extra power they store.

i think under the hood will be a good idea cuz like marshall said it can help filter the ac and it will help the alt when it gets stressed by demand of power well i think that way im not sure

1) a cap has nothing to do with the starting of the engine, hot or cold.

2) a cap under the hood is a bad idea because the main purpose of the cap. is to smooth the ac ripple and deliver bursts of power at times of high demend when needed by the amps. thats why you want it as close to the amps as possible, for the power going from the cap. to the amp has the shortest distance to travel. it in no way helps relieve stress from the alt., just adds to it if the alt. isn't large enough.

1) when the climate is cold the amps of the batterie gets lower why u think batteries shows coldcrakin amps when u start the enine the batterie give alot of power in one burst to power the engine and wit a cap it will help alittle better to charge and it will help to discharge
2) and cap can filter the ac thing and that will help the noise when u push the gas and it will help to get cleaner power to the headunit cuz is the main unit of the sound system.

i know it has to be as short as posible but can be near the startin batterieand it will help get cleaner output to the other accesories and im gonna put a second batterie or another cap close to the amps

LIlrob, listen to what they are telling you! Fck that guy that took those pictures, looks to be of a Grand prix GT. That cap should never have been wire-tied to the after market steel tower support rod it is a fire waiting to happen. By the way, I think he is running a stock alt also Here is a picture of my engine which is close to his but MORE balls, note the difference of his alt to mine (300A) and also note, NO CAP! Polo. :-O

Oh and also if I am not mistake, the increased heat will bring up the ESR value of the cap, coupled with the extra length of the power wire will probably make it useless not to mention cut its life really short...JMHO..Polo :-)

I suggest you let it collect dust some more than putting it on the truck

Do the big three, use a deepcycle battery and get a HO alt. After you have done that then maybe you can get a cap and place it 6" from you amplifier(s). Use a max of three caps to keep the ESR down (resistance). Polo..
