If the subwoofer has a 4-ohm impedance, the amplifier should have a matching 4-ohm impedance as well.

How Many Amperes Does a Subwoofer Use?

A subwoofer typically consumes around 4-5 Amperes of current. However, if you have a more powerful subwoofer, it may draw up to 10 Amperes. The exact amount depends on factors such as the impedance and size of the subwoofer.

How Many Watts Do I Need for Two 12-Inch Subwoofers?

To determine the necessary wattage for two 12-inch subwoofers, you should check their RMS values. For instance, if you have a pair of Kicker CompVR CVR122 subs rated at 400 Watts RMS each, you will need a total of 800 Watts RMS or slightly higher. Additionally, these subs have a 2-ohm impedance, so your amplifier should also have a 2-ohm impedance.

What Size Amplifier Do I Need for a 10-Inch Subwoofer?

When powering a 10-inch subwoofer, you don’t necessarily require an excessive amplifier. For instance, if you have a Kicker CompC Single 10-Inch subwoofer with a maximum power rating of 500 Watts and an RMS rating of 250 Watts, you’ll need an amplifier with an RMS output of 250 Watts or slightly higher. It’s also important to match the impedance, so the amplifier should have a 4-ohm impedance, which aligns with the subwoofer’s impedance.

How many watts can a car battery handle?

The maximum wattage a car battery can handle varies depending on factors such as the alternator’s amperage output and the reserve power of the battery itself. In a 12-volt system with a 90-amp alternator, the power capacity is approximately 1080 watts. A standard car battery typically has around 500-600 amps of reserve power, which translates to around 6000 watts. However, it’s important to note that pushing the alternator to its limits can drain the battery and potentially cause damage to both the battery and the alternator. Upgrading to a higher amperage alternator, such as a 140-amp alternator, can provide additional power for periods of heavy draw.

When it comes to subwoofer sound output, it is not solely determined by the power rating advertised by manufacturers. Peak power ratings can sometimes be exaggerated for marketing purposes. The key factors that contribute to a subwoofer sounding loud are the sound pressure level (SPL) and the subwoofer’s power handling capability. Sound is created through the vibration of an object, which affects the air molecules nearby, causing them to move in sound waves. The more air molecules that are moved, the louder the sound waves become. The ability to move air and create sound pressure is measured in SPL using decibels.
