What is a good alternator for car audio? Best Alternator for Car Audio-To keep the melodies running
Can a sound system mess up an alternator?
However, subwoofers combined with their amplifier and the corresponding amplifier can damage your alternator if it draws too much power from your battery. And this can cause the alternator to overheat and potentially damage. An alternator works with your battery to charge your vehicle's electrical systems.
What happens if you put a higher amp alternator on my car?
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 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.
Is a 160 amp alternator good?
Is a 160 amp alternator good? The high amp alternator will give you more replacement juice if you are running any high amp load appliances. 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 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.
Can car stereo drain your battery?
Can a Car Radio Drain the Battery? Yes. When a car stereo, radio, receiver, or head unit drains, your battery is due to a process called “parasitic draw.”
Are subwoofers illegal?
Sound systems are generally perfectly legal as long as they aren't impacting the quiet enjoyment of other individual's homes. Otherwise, you could potentially run into some trouble.
Why do my lights dim when my subs hit?
The problem is being caused by the large, sudden current draw that your subwoofer amplifier requires when bass notes are played at high volume. If your electrical system (especially your alternator) can't keep up then your vehicle voltage will drop and cause the headlights to dim.
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.
How big of an alternator do I need for 2000 watts?
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 size alternator do I need for 1000 watt amp?
As a general rule, you need about 100 amps of current for every 1000 watts of power generated. Add that to the base electrical requirements of your vehicle for the total amount of amp-hours you need for your system. Example: You plan to install a 2,000 watt amplifier.
Can I install a bigger alternator?
A higher amperage alternator will not pose any problems to the vehicle's electrical system. For example, you may have a 100 amp alternator in your vehicle and the turn signals have small wiring and will only use 10 amp of power. Upgrading to a 200 amp alternator will not affect these components.
Do I need a bigger alternator for two batteries?
The alternator registers these two batteries as a single large battery and charges them the same. The batteries self-regulate the amount of current they take as they charge. This means that a single alternator is effective for multiple batteries.
How many watts can a alternator handle?
A compact car with a 35-amp alternator can accommodate around 150 X 2 watts of power, while a Sport Utility with a 145-amp alternator can handle a 600 X 2 watt system. A capacitor can help if your system is drawing a little too much power.
Do I need a 160 amp or 145 amp alternator?
No need to go higher amperage so it's whatever you want. You only need higher amperage if you have a lot of off road lights, a stereo system, or a plow.
How many watts can a 120 amp alternator handle?
thats an average between output surges. Thats just sort of a relative rule of thumb. The other sorta relative rule of thumb is that 10 amps can translate to somewhere in the neighborhood of 100 watts so a 120 amp alternator could do 1200 watts.
How many batteries do I need for 5000 watt amp?
You will need at least one 450-500 12V battery or two 210 12V batteries to supply 5000 watts of power for 30-45 minutes. If you'd like an hour of 5000 water of power, you'll need a 750ah 12V battery.
What is the big 3 upgrade?
A big 3 upgrade will allow more current flow to all of your stereo components, improving your electrical system by ensuring more consistent voltage. This upgrade entails replacing the three main cables in your electrical system with 4 gauge or 1/0 wires.
Is the big 3 upgrade necessary?
Big Three Upgrade. When installing a car audio system of 1200 watts or more, you really should do a Big 3 Upgrade to improve your car's electrical system before. This may seem daunting to some, but it's so worth it. Factory wiring is insufficient for running anything but basic audio systems.
How many batteries do I need for a 2000 watt amp?
When it comes to batteries, a 2000 watt inverter needs 24 volts to generate power. You would be able to use 100Ah x 24Ah if you used 2 batteries of 12 volts 200Ah.
How long can car radio run on battery?
According to experts, when using a standard car battery, the radio will run for about 8 hours before the car battery runs out. However, if your car has an amplifier and a subwoofer, the radio's listening time before the battery is discharged is reduced to about 6 hours.
How can I listen to the radio without draining my battery?
Running a radio with the engine off in your car can theoretically drain your battery, even if it is unlikely for most modern cars. If your car refuses to start after you've been listening to radio with the engine off for a few hours, you may have a problem. The best option will usually be to jump your car's battery.
Are exhaust whistles illegal?
Exhaust modifications are illegal only if noise emitted is over 95 decibels. Keep in mind California smog laws or other legislation may still make your custom exhaust modifications illegal. All vehicle exhaust systems must have mufflers. Any bypass, cutouts, and especially whistle tips are not permitted.
Are noisy exhausts illegal?
It is illegal to modify a car's exhaust system to make it noisier than the level at which it passed type approval with. Most cars over 10 years old will not need vehicle approval however, including imports, so it's unlikely a classic car owner will know for sure just how loud their exhaust is.
How do I make my car louder legally?
Is a capacitor needed for subs?
Capacitors store electricity as instant power available for your amplifier. If the amplifier draws more current than is available from the electrical system directly, the capacitor covers the difference up to its stored capacity. The battery is not overloaded and the car voltage remains steady.
How do I stop my lights from flickering when bass hits?
Do capacitors help car audio?
Yes, it stores power to an extent, but it does not function in the same way as a battery. Capacitors are advertised as a way to store extra current and deliver it to your amplifiers when they pull large amounts of power to stabilize your electrical system and current draw.
How many amps should my alternator be at idle?
Most late model alternators produce 120 to 155 amps or more. Current output increases with engine speed, from around 20 to 50 amps at idle up to the unit's maximum output at 2,500 RPM or higher (refer to a service manual for the exact charging output specifications for your vehicle).
Can an alternator put out volts but not amps?
If the voltage is 14+V and no amps are being drawn then the problem is almost certainly not with the alternator. If the batteries can draw more current than the alternator can supply then the voltage won't climb to 14. Since the alternator was putting no current out the batteries were charged.
What charge should an alternator put out?
A good alternator should put out between **13.5-14.5 volts. Stress test the alternator - Place a load on the alternator by turning on the headlights, the radio and the air conditioning. The voltage should remain high with these circuits on.
Can you run 2000 watt amp on stock alternator?
A 2000W audio system at charging voltage is drawing about 142 amps. The stock alternator outputs 160A, so my system would be using up 88% of my alternator's power, which would be fine if there wasn't a car needing to be powered.
What is the advantage of a higher amp alternator?
A general high output alternator will provide more amperage, and in other words more power, but it will also increase the engine speed, proving itself capable of generating more power, but not being very useful in the long run.
What is a 220 amp alternator?
