Car amps normally work off of a range of voltages, not just 12 volts, although that's used as a general reference. In fact, as a vehicle's engine runs the alternator charges the battery and the voltage can range from near 12V to about 14.4V.

How many volts should a car amplifier have?
Usually the range is somewhere between 10.5-16.5 volts. A regulated power supply will put out the same power regardless of the vehicle voltage.
How many volts do amplifiers need?
For standard 4-ohm speakers, it takes a peak-to-peak voltage of almost 60 volts to deliver about 100 watts to your speaker. In most amplifiers, this voltage is configured as +30V and -30V, relative to the ground reference voltage of your vehicle chassis.
How can I power my car amp in my house?
You'll need a +12V AC-DC power supply with enough current to run the amp. Not just any AC/DC 12V adapter will do as you'll see later. Turning the amp on/off: This is actually really easy! You can simply disconnect your DC power supply and let the amp shut off or use a simple switch to turn the amp on and off.
How much voltage drop is acceptable in car audio?
Registered. A safe drop would be no more than 3 percent. 5 percent is pushing it. Don,t ever get below 11 volts though.
Will 1000 watt amp drain battery?
A 1000 watt Amp won't drain your battery, but a Capacitor is highly recommended.
How many amps does a 2000 watt amplifier draw?
You have the voltage (nominally 14.4 volts) and the power (2,000 watts), so the answer is 2,000/14.4 amps. In other words: 140 amps, give or take.
How many amps does a car amplifier need?
A typical car amplifier requires anywhere from 10-30 amps. (You can check how much amperage you need by looking at the fuses usually located close to the inputs on your amplifier.)
Are car amplifiers AC or DC?
Car amplifiers are designed to use the direct current (DC) from the car's battery and alternator for power. This is different from a home electrical system, which uses alternating current (AC) and provides 110 to 120 volts at a lower current.
How many amps is a car battery?
An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on.
What size amp do I need for a 1000 watt sub?
For a 1,000 Watt powered sub, you would need about 10 Amperes at 120 Volts, assuming digital amplification.
Can low voltage damage amplifier?
Administrator. 1freedude said: As the volts go down, the amps will rise to maintain the same, static, power. This rise in amps at lower volts will do the damage.
Can I ground amp to battery?
The best way to ground your car stereo components is to run a 10 or 12-gauge wire from the amp, and 12-gauge from all other components, such as head unit and active crossovers, to a central location. Then run a single ground to the best source of ground, the negative terminal on your car's battery.
