Caps

Hey, I'm hooking up 2 amps, to 4 subs, and I'm planning on getting a cap. Is 1 cap enough? Or should I run 2?

How much power are you running? A cap may or may not help what you think might be wrong... What are you trying to cure/fix/prevent? A little more info, please.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Better off getting a larger alternator, this is the first step to "stiffening" your power supply. You only have 700 watts worth of output, which should be somewhere around 1000 watts of input. 1000/14.4=69 amps of current requirement. How big is your stock alternator? Anything around 100 amps should be plenty. The general rule is 1 Farad per 1000 watts, but as I said, look into your alternator and battery before you spend money on a cap, which may or may not help anything at all.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I agree with them. A lot of the people that I know that have capacitors claim that they are helping their system, but I think it is just a big hoax. If you think you'll need one then go for it. It is your money. So far the only thing I have seen work decently well is something called a batcap, which is basically a frickin' huge capacitor with the storage and output equal to that of a small battery, though the price is much higher than a battery. Alternators can be a bit pricey, especially if you won't be doing the install on it yourself. Go for a nice battery first, maybe a dry cell battery (i.e. Optima) Even upgrading your "Big Three" would be a cheap way of getting some extra output.
