well, your lookin at RMS when it comes to speakers and amps, if you bought a 800 watt amp, you would be looking at 400 RMS just as you do with your speakers, i would recommend a 1600 watt amp, just for the fact that you always want a little play room with your amp, this way you wont blow the amp, (amps are more expensive than speakers), and if you decide that you want to get bigger speakers, you will not have to replace the amp. But all in all, i would say anywhere from 1200 to 1600 would do just fine for your sub..-Shocker
The rated voltage of an appliance is no guide to its power rating. To find out the power (watts), you will need to look at your washing machine's nameplate, which will indicate both its rated voltage and its rated power.
Most power amplifiers will handle a load of 6 ohms. The spec you need to look at is the power handling of the speakers. If they are rated for 100 watts program power, then look for an amplifier rated for 100 watts RMS output. Any amplifier can be connected with adapter cables to the typical 1/8" output of your computer.
Connect the sub woofer to the equalizer or amplifier. The positive wire will need to be connected to a power source. Connect the ground wire. Connect the auxiliary wire to the amplifier.
The formula for watts (or power) is Amps times voltage. Therefore with a 6 amp draw times 120 volts would be about 720 watts. A 1000 watt power inverter would do the job.
The speakers will work with any amp that outputs less power than 700 watts.
Find out what the rms is for that sub woofer,if it'1000 then find out what the max is,then you could go between the rms power and the max power to get the right amount of watts.
Any amp will power a 15" sub. What you need to know is what is the RMS of the 15" sub. Lets say its 200 watts RMS than you will want a max of 200 watts for your amp.
Any electronics repair shop should be able to provide you with a 12 inch woofer. The speaker is rated at only 50 watts (100 w peak ), so you won't need a super power handling driver.
Impossible to know. You need to know both the voltage and current draw to calculate power (watts). Power in watts = Volts X Amps
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.
To convert voltage to watts, you also need to know the current in the circuit. The formula to calculate power (watts) is: power = voltage x current. As voltage alone is given, you would also need the current flowing through the circuit to accurately determine the power in watts. Without the current value, it is not possible to convert voltage directly to watts.
Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80& of maximum. You need 14 AWG gauge wire.
To calculate the number of watts in 0.1A, you need to know the voltage of the circuit. The formula for power is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amperes. Without knowing the voltage, it is not possible to determine the power in watts.
To power your speakers, and to ensure that your amp has enough power to power your subwoofers, you would need at least an amp of 750 watts true power.
Read your power listing on the Dell; it could be on the back of the computer, or many times it is on the 'wart' part of your power chord (also can be on the manual). that will tell you how many watts pull you have. The Schumacher does 410 watts continuous, and 800 peak (not reading the manual, but just looking 'as advertised,' though you could look deeper into that) and the watts pull on your dell would need to be below the 410 continuous (which I am sure it is). The 'startup' sometimes could be two to three times the continuous 'watts pulled' by your dell. You should be fine with this inverter, but read the manual of the car you are using because usually they tell you how many watts draw is the maximum on the system off of your cigarette lighters. My max on my car is 160 watts. If your dell is above the watts max off your car system, you can consider 'hardwiring' it straight to your battery with a 'inverter cable kit' that has 10 ft inverter cables with 4 gauge wire to permanently install your inverter in your car.
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.
