14.4 volts is the standard for measuring amplifier output (thanks to CEA finally setting a standard!) That does not mean that the average vehicle is going to consistently (or ever) put out that high of voltage so don't assume your amps NEEDS it. It is important to get as high of voltage as possible though, so investing in an aftermarket alternator is a must if you have a true high-quality, high-power system. A beefy alternator will also address other concerns associated with excessive current draw such as dimming dash and head lights. Amateurs will often use capacitors which are really just band-aids for these problems.

Other two answers are right.
Make sure your alt. is up to par. Check the fuse size on the amp and make sure your alt. puts out about 20% more than that. If so, do the Big3 Upgrade. If not, get a HO alt. and do the Big3 Upgrade.
The Big3 Upgrade:
1. Charge wire from alt. to battery.
2. Ground from battery to frame.
3. Ground from frame to engine block.
Do these in 4g or larger wire. Use copper lugs. You can replace factory grounds or simply add-on to them.
This will give you the benefits in which crapacitors are sold for (they don't work). -Dimming headlights, voltage drops.
Good Luck!

Start the engine.
Amplifiers are generally rated at 14.4 volts because the alternator generates that much voltage while the engine is running.

uhhhh get a high output alternator, generally ur gonna push like 13.8 amps. it doesnt really matter how many volts it gets its about how many amps u get. if ur voltage falls too low ur car will die. so jz get a highoutput alternator. uhmmm take the total amount of watts rms, multiply by 2 then divide by 13.8 then divide by 3 and thats how many amps ull suck up. make sure its no more than 40 percent of ur alternators capabilities. either way only way to make sure it HITS HARD is to jz give it real juice. ya dig?

I would suggest, going to the auto parts store and buy an alternator bigger than the one you have, that puts out more amps.

you need a accuvolt if you are looking for that voltage
