4 channel amp to 1 dvc sub series#

You could run a P500x1bd at 1 ohm, or you could run a P1000x1bd at 2 ohms. Let's say you have a Rockford Fosgate subwoofer that can handle 500 watts. You can also save some money by wiring your subwoofers to a 1-ohm load. There is no substitute for power if you are looking for maximum volume and at 1 ohm, the amplifier will put out more power. At 1 ohm, you will get more power output from your amplifier and your subwoofers will play louder than if you wired them to a 2-ohm load. If you like loud bass, and you are trying to get maximum output for your money while also getting maximum output from your subwoofer(s), get an amplifier that is 1 ohm stable, and select subwoofers that will allow you to wire them to a 1-ohm load. Are you going for the best possible sound quality? Are you looking to maximize bass output for your money? Will your ear be able to tell the difference in sound quality? The case for 1 Ohm: Maximum Volume Unfortunately, the answer is 'It Depends.' The right answer for you will depend on the subwoofers, the amplifier, your budget, and what you are trying to do. This is a situation where they limit the current draw in order to make sure that the amplifier does not overheat and burn itself out.

You might see 300 watts at 4 ohms, 600 watts at 2 ohms, and 800 watts at 1 ohm. Now amplifiers are not all the same and the circuit design is not always linear. But as we saw above, as resistance decreases, current increases, and therefore power increases.

At 3 ohms:Īt 1 ohm we have 12 amps, 12 x 12 = 144 watts.Īs you can see, as you drop the resistance, the power output in watts increases. At 2 ohms:Īt 2 Ohms we have 6 amps, 6 x 12 = 72 watts. So from the equation above: At 4 ohms:Īt 4 ohms we have 3 amps. Since on a car, we will assume it is 12 volts and the vehicle is not running.

A = Amps which is the amount of current.

V = Voltage which is constant at 12 Volts.

Power equals the voltage multiplied by the current. At 2 ohms:Īgain, we will divide 12 by 2 and we have 6 amps of current Finally, At 1 ohm: If we divide 12 by 4, we get 3 amps of current. Cars are considered '12 volt' but most are running at 14+ volts when the car is on and the alternator is running. Let's assume the voltage remains constant at 12V. Ohm's law states 'Voltage equals the current multiplied by the resistance.' E=IR The first place to start is with Ohm's law. The output difference between 1, 2, and 4 ohms will vary depending on the amplifier brand, amplifier model, and the technology.

Additionally, on some amplifiers like the JL Audio HD series or the Rockford Fosgate Power Series, the output is the same at 1 ohm, 2 ohms, and even 4 ohms. The difference in the power output may be as little as 10% or, you might see twice the power at 1 ohm that you do at 2 ohms. The difference between a 1-ohm and 2-ohm will depend on your amplifier. Usually, subwoofers are wired to either a 1 ohm or 2-ohm load in order to maximize the power output from the amplifier.īut, is it better to run an amplifier at 1 ohm or is it better to buy the bigger amplifier and run it 2 ohms? The subwoofers you select and how you wire them will determine the impedance or load, that the amplifier sees. Then there are dual voice coil subwoofers with dual 2-ohm, dual 4-ohm, dual 8-ohm, or dual 1-ohm voice coils. There are single 4-ohm voice coils, single 2-ohm voice coils, even single one-ohm voice coils. WARNING: Cancer and Reproductive Harm - selecting your subwoofers and the amplifier to power them, there are so many choices. The warning is part of our ongoing effort to comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986 (known as 'Proposition 65'). Why do you see the warning on our packaging and website? Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including electronic equipment, and warnings can be seen posted throughout California in a variety of establishments such as buildings, hotels, restaurants, coffee shops, and stores. The list includes naturally occurring and man-made chemicals. There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. Businesses are required to provide warnings to comply with Proposition 65. Proposition 65 is not a product safety law, but rather a 'right-to-know' law. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels. Proposition 65 is a California law that applies to companies selling products in California.
