!!!!!!!!!!whats a good capacitor for this amp!!!!!!!!!!!?

whats a good capacitor for an orion d5000 amp,(2500watts) i like the boss 3.5 or the kole audio 4.0, there pretty cheap on sonic electronix 65 dollars|||Get the Boss 3.5.|||look into kenwood, rockford|||They all do the same thing. As long as the cap can handle 2500watts then I'd go with the cheapest.|||Honestly I would suggest getting a 2nd battery instead of a cap. Something decent like Optima Yellow top, or a Kinetik 1400 or larger....|||If your total system power is 1200 watts RMS or more, you will need to:





1. Upgrade the "Big 3" - that is to replace (or add to) the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis.





2. Upgrade to a yellow top battery





3. Upgrade the alternator to a high output alternator








Failure to do this will result in the early death of the alternator as it will eventually fail.





Here is a guide that will calculate what size alternator and power wires you need http://www.box.net/shared/uchv4dbk88





You will need Microsoft Excel. If you don't have Excel, use this link http://www.box.net/shared/nkkw1dhk4g





A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off.





A capacitor is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing else. If the current isn't there, a cap won't help.





The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.

The thing is, people get confused in the real purpose of a cap. It is not used to cure or prevent dimming lights.





To undertsand the purpose you need to understand how they work.





A cap does it's best to keep the voltage at a certain level, but if the voltage changes so will the cap voltage. The cap just makes the change smoother. The diming light syndrome isn't a voltage issue but rather a current (amperage) drop. The voltage simply follows what the current does. A cap does not help this situation at all. A cap doesn't provide more power nor does it try to correct it.





A cap is perfect for a noisy voltage line or if the car has fast, erratic voltage spikes/drops. This is why caps are used in AC to DC power supplies as they are used to smooth out the DC ripple for a more smooth DC output.





The ONLY cure for dimming lights is a more hefty amperage source, the alternator.





The REAL powerplant of the car is the alternator. The ONLY purpose of the battery is to start the car and run the accessories with the engine off, nothing else.
