Ok...let me rephrase. It is reccomended to replace the alt. if running more than 800/1000 watts. In some cases (trucks) they have bigger alternators and you can get away with not having to change it. But in MOST cases, the alt needs to be replaced. Capacitors are just a bandaid. I would not reccomend one.
i personally love caps....just my opinion. they can make a big difference and they are just intended for extra juice during peak power draw and just for a short period. granted they are always part of the power supply line but in some cases well worth installing.
In some cases they are good, like in competition when all you need is a short burst of power. But in most cases, just upgrading the alt is the better route to take.
ok i installed it and it seems to work fine...i'll upgrade my alt anywayz so i'll feel more comfortable with my old truck. but anyway thanks for the help....
I would upgrade the battery first before the alternator or a capacitor. There is actually a huge difference between a normal car battery and something such as an Optima Red Top or Yellow Top.
