capacitor? or is my car able to give sufficient power?

I have a 2000 Bonneville SSEI and I will be running 900 watts RMS my car has the original alternator and this is the battery CCA: 880; Battery is vented to outside of vehicle; 30 Minute Installation; Located under rear seat; OE Group Size: 79; OE CCA Rating: 880 I believe it's some knock off from advanced auto parts....however the damn thing was somehow $150!!!! Would this be fine or would a capacitor help at all.... I'm new to this side of car audio.. Thanks!!!!!!!!

lmcaraudio 		GM Cars usually have good alternators so you should be fine. I cap could help but would not make much a difference at all. If you do buy one check ebay because they are a lot cheaper than going to a store to buy one. Unless your running big power you should be all set unless you notice the lights dimming when a big bass note hits.

lmcaraudio 		if your lights dim on your vehicle upgrade your big 3 to larger gauge 1/0 is reccomended Big 3 is +batt cable to alternator -batt cablee to engine block - engine block cable to chassis upgrade those to a larger gauge to increase current flow

lmcaraudio 		The thing is, people get confused in the real purpose of a cap. It is not used to cure or prevent dimming lights nor will it change the way the system sounds (both are misconceptions). 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.
