What size alternator do I need for car audio?

Typically, a 250-300 ampere high output alternator should provide enough power for your car’s power needs in addition to the new audio system.

What does a high output alternator do for car audio?

High Output Alternators increase the amperage of your system. Relying on a stock electrical system for the massive amperage that car audio amplifiers require, while still supplying your vehicle with the current it needs will result in low voltage and other problems.

Can I run a higher amp alternator on my car?

And it basically operates off of supply and demand. That is, your alternator will only supply the amount of amperage a particular component demands—and no more. So high-output alternators will not harm your components or charging system, no matter how high you go with the amps.

What size alternator do I need for car audio? – Related Questions

Can a battery be too big for an alternator?

Plus, even if it physically fits in the compartment, an oversized battery could cause other issues. Manufacturers precisely match their alternators and batteries to the vehicle’s power requirements. A mismatched battery/alternator combo could cause your alternator to overheat and shorten its life.

How many amps is too much for alternator?

If your vehicle’s electrical load exceeds the amperage—or maximum capacity—of your alternator, you’re asking for trouble. Most factory alternators are rated at 65 to 100 amps and are capable of handling a vehicle’s basic accessories—headlights, gauges, fuel pumps, transmission, A/C, etc.

Will a high output alternator overcharge my battery?

Can a car alternator overcharge the battery? Yes, it can fail internally (the “ground” lead from the field slip ring can short to ground and cause the unit to run full current continuously. The internal regulator can fail and cause overcharging.

Does a high output alternator increase horsepower?

On some applications, a high-amp alternator can actually add horsepower to your engine’s performance.” Sure, it’s nominal, but, when it comes to horsepower, every bit helps.

Will a higher amp battery damage my car?

As several people have stated, no, a larger battery will not harm your alternator (or other electrical components), provided that it is putting out the correct voltage.

What size alternator do I need for a 1200 watt amp?

Something in the 150A range should be more than enough.

Is a 250 amp alternator good?

Most stock alternators are in the 80-120 ampere range and can only supply about 40% to 50% of that for non-automotive uses like amplifiers. A 250 or 300 ampere aftermarket high output alternator should provide enough power for all your car’s systems and your high-powered stereo too.

Can subwoofers damage your alternator?

Is it possible to harm your alternator by using subwoofers? Subwoofers don’t have the ability to damage your alternator on their own. However, if a sub and its amplifier draw too much power from your battery, they can cause harm to your alternator. This might lead to overheat and can potentially destroy the alternator.

Is the big 3 upgrade worth it?

The “Big 3” upgrade can not only improve the performance of your audio system, it can also enhance the performance of the entire electrical system for your vehicle (which can lead to improved fuel economy or additional horsepower). In other words, upgrading the “Big 3” is almost always a good idea.

Will dual batteries hurt my alternator?

Most alternators are designed only to charge one lead acid battery, and any more can cause it to overheat and melt its winding. However, a dual battery setup shouldn’t hurt your alternator as long as it’s wired correctly and you have the right equipment in place.

Do you get paid for Big 3?

Multiple reports have indicated that Big 3 players earn $10,000 per game, plus additional bonuses based on team performance. That means players can reach $100,000 in a single season.

How big of an alternator do I need for 5000 watts?

Ultimately you need a 5000 watt alternator for a 5000 watt load, but if you consume 5000 watts inside your car it will be effectively an oven and you will die soon. You will also need special signalling to your engine ECU to tell it that the AC is on so that it doesn’t stall.

How many watts does a 200 amp alternator produce?

A large alternator can be 200 amps or more. 14.4 volts x 200 amps = 2880 watts.

What is a big 3 upgrade?

The upgrades in the Big Three are: The run from the alternator chassis to the negative terminal of the battery. The run from the output of the alternator to the positive terminal of the battery. The ground connection from the negative terminal of the battery to the chassis of the vehicle.

How many watts can a 400 amp alternator handle?

400 amps at 12 volts is 4800 watts, you would need at least double belts to turn the alternator.

How do I make my alternator high output?

Installing a smaller-diameter pulley on the alternator shaft speeds up the rpm of the armature so more amps are produced at that engine rpm. A higher alternator speed also helps its internals cool better under load because its cooling fan is spinning faster.
