What size alternator do I need for 2000 watt amp?

To figure out how much capacity or amperage the alternator must deliver, determine how much extra power the audio system demands on top of the current system. For example, if you installed a 2,000-watt amp, assuming a nominal voltage of 13.5V, you'd add roughly 150 amps of demand to the electrical system.

What battery do I need for a 2000 watt amp?

The easiest rule of thumb to follow with electrical upgrades is that for every 2000 watts of RMS power you add, you'll want to add 100aH (amp hours) of AGM battery.

How big of an alternator do I need for 3000 watts?

3000 watt / 12V is equal to 250A. A 250A alternator is needed to keep up with it. Since your engine would have to work just as hard as any portable 3KW generator to keep up with the amplifier, you would need a large fuel tank.

What size alternator do I need for 1000 watt amp?

If you've read this far and are starting to rethink 150's, hair tricks, and broken windshields, you can still enjoy considerable bass with a single high output alternator in your car or truck. As a general rule, you need about 100 amps of current for every 1000 watts of power generated.

How much amp alternator do I need?

The amp rating of the alternator is matched to the vehicle's electrical system. Older vehicles with fewer accessories may only need a 70- or 80-amp alternator, while a newer vehicle with lots of electronics and accessories may need a 120- to 160-amp alternator.

How to Choose a High-Amp Alternator

Will a 2000 watt amp drain battery?

Answer provided by

Usually, a 2,000-watt car amp will draw about 159 amps. However, this assumes that your car battery is fully charged and operating at 12.6 volts.

Can an alternator be too powerful?

You can never have too much amperage when it comes to alternators; therefore, you never have to worry about choosing an alternator with too high of a rated output. Here's why: Amperage is basically the amount of electrical current your alternator can supply. And it basically operates off of supply and demand.

How many watts can a 80 amp alternator handle?

it depends on what size your alternator is. considering its a small car probably around 80amps. thats good enough for around 500 watts rms.

How do I determine the size of my alternator?

As a rule of thumb, 12-volt alternators use one horsepower for every 25 amps of output, or to put it another way, their ratio of output to horsepower load is 25:1. So, when selecting a new alternator, you need to size it for the limits of the capacity of its drive belt.

What size capacitor do I need for a 1500 watt amp?

A: The rule of thumb is to put in 1 Farad of capacitance for every 1,000 watts RMS of total system power. But there is no electronic penalty for using larger value caps, and in fact, many see benefits with 2 or 3 Farads per 1,000 watts RMS. The larger the cap, the more charge is available for the amp when it needs it.

How many amps does a 2000 watt inverter draw?

If you max out the inverter at 2000 watts, you are pulling 2000 watts /12 volts = 166.6 DC amps per hour.

How many amps do I need for a 3000 watt system?

For example, 3000 Watt equals to: 25 Amps, if you use 120 V.

How many batteries do I need for a 2000 watt inverter?

Helpful Expert Reply: Typically two batteries are needed for a 2,000 watt inverter like the part # 34278156 that you referenced.

Do I need a bigger alternator for two batteries?

A car alternator will be more than capable of charging two batteries. However you need to be more careful about connecting two batteries together if one is charged and the other is not.

How do I know which alternator to buy?

If for any reason you cannot find your alternator by entering your vehicle's year, make and model, you can find the best alternator for your vehicle by its Original Equipment Manufacturer (OEM) number. The OEM part number can be found directly on the part itself.

How do I choose an alternator?

Is a 160 amp alternator good?

The 160 amp is known to be used on emergency vehicles that are at a standstill and still running lots of 12v power thru said appliances.

How much horsepower does it take to run a 100 amp alternator?

An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP. For a long time, most alternators don't operate at full output.

How many amps does a 1000 watt car amp draw?

If the amplifier uses a 12V supply and puts out 1000WRMS, it requires 83 Amps.

Do you need a bigger alternator for sound system?

If your sound system demands more power than your stock alternator can supply, then you will benefit by upgrading to a higher output alternator.

Why would you need a bigger alternator?

You're able to reduce the depth of a battery's discharge—also known as cycling. That's because an oversized alternator produces more output at lower speeds, including idle. That increased output prevents the battery from having to help supply the load—and this keeps it at a more ideal state of charge.

Is 15 volts too high for alternator?

So, to answer your question, Yes, 15 volts is too high. Most car alternators, that normally recharge your battery after every start, and provide power while the engine is running, are normally voltage regulated to about 13.8 to 14.0 volts.

Can an alternator fry a computer?

The only way amperage can damage a circuit is if the circuit is not fuse protected and a power wire grounds or shorts out. This causes the massive amount of stored battery current to travel the circuit burning everything in the path. This scenario can happen with or without the vehicle even on.
