# Question: Can A Sound System Mess Up An Alternator?

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

3000 watts / 12V = 250A.

You’d need a 250A alternator to keep up with it.

You’d also need a much fuel tank, since your engine would have to work just as hard as any portable 3KW generator to keep up with the amp..

## How many batteries is 5000 watts?

The number of batteries will depend on the DC input requirement of the inverter. Usually, a 5kW inverter will have a 24v DC input requirement. So you will need two 12v batteries. Some models use 48V DC, in which case you will need four 12V batteries.

## Will Subs drain my battery?

If it’s properly installed it shouldn’t be draining your battery while the car is off. If you’re listening to music in the acc position then yeah that’s definitely gonna drain your battery. Also the amplifier is the one that’s connected to the battery, so yes that wire is normal.

## How many 200ah battery can power a home?

Originally Answered: How many 200Ah batteries can power a home? A 200Ah, 12V battery in practice will give you about 12 x 200 x 0.5 = 1200Wh of power. (The 0.5 is used in the calculation as a Lead-acid can supply only about 50% of its capacity.

## What can ruin your alternator?

One of the most common failures is bearing failure. The needle bearings that allow the rotor to spin freely inside the stator can break down from dirt and heat. When the bearings fail, the rotor will not spin efficiently and can eventually seize. Usually an alternator with bearings failure makes a loud grinding noise.

## What are the signs your alternator is going out?

Symptoms Of A Bad Alternator The most common symptom is that the vehicle’s charging system will show an issue as the battery-shaped warning light comes on on your dashboard. If this light doesn’t come on, the “CHARGE” icon could also come on while you’re driving.

## How far can a car run with a bad alternator?

Starting with a fully charged battery you will probably get 100 Miles before it wears down too far. It also depends greatly on not running headlights or running lights. If you have a car that always runs with the headlights on, and if your battery is several years old, 50 miles might be a better estimate.

## What is the most powerful alternator?

— Remy International Inc., manufacturer and distributor of Delco Remy brand heavy-duty starters and alternators, has released its most powerful and efficient alternator yet to the aftermarket. The Delco Remy 55SI has a durable brushless design and is rated at 420 amps at 12 volts and up to 275 amps at 24 volts.

## Will a capacitor help my alternator?

Capacitors will not make up for an inadequate power source. They WILL filter the power, providing a cleaner power flow to the amps, as well as filtering the draw from the battery & alternator.

## How many volts can a car alternator produce?

14.5 voltsThe alternator is designed to keep the battery charged to at least 12.55 volts, with a maximum of approximately 14.5 volts. The amperage output is usually listed as the maximum output of the alternator.

## Can subs ruin your alternator?

Subs (being inductive) cause a lagging power factor causing the amp and battery to draw more power than is required. A cap is dangerous as it gets charged up but as I said a cap is not a replacement for a battery. it smothes out voltage spikes, making it easyer on your battery and alternator.

## Will dual batteries hurt my alternator?

You should not incur any issues using a secondary battery with a battery isolator. It will not cause any damage to your alternator. For your edification, it won’t be using wasted energy, but your engine will probably using a tad more gas to operate the alternator, which will have to do more work.

## How can I tell if my alternator is going bad?

If an alternator is giving a low charge it will but a load on the engine trying to ineffectually charge a battery and the battery will slowly die as the alternator gets weaker and weaker and cannot sufficiently recharge the batter.

## 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 batteries do I need to run a 2000 watt inverter?

Now come to batteries, a 2000 watts inverter usually needs 24 volts to generate power. 2 batteries of 12 volts 200AH (you can use other capacity too) in series connection needed and out of them you would be able to use 100 AH x 24 volts that is 2.4kWh.

## How many 12v batteries are needed to power a house?

Number of Batteries A battery bank designed to power an average American household for three days would need to supply 90 kilowatt-hours of energy. The battery from the previous example can supply 2.4 kilowatt-hours, so this system would need 38 batteries.

## Do I need a bigger alternator for my sound system?

The alternator is the ultimate source for all of your vehicle’s power when it’s running. … If your sound system demands more power than your stock alternator can supply, then you will benefit by upgrading to a higher output alternator.
