How many ohms in 800 watts?
4 ohms
How much ohms does 1500 watts speaker has?
The wattage and ohms of a speaker are not related; the resistance for speakers is usually 4 or 8 ohms.
If you have 500 watts at 4 ohms how many watts do you have at 8 ohms?
250 watts approximatelyI assume you have a constant voltage supply. According to P=V^2/R => P*R=V^2, you have a 44.7 volt supply. If you change Resistance to 8 ohms, P=44.7^2/8 => P=250 watts.
How many watts does the Rockford Fosgate Power 150a1?
75 x 1 Watts RMS @ 4 Ohms 150 x 1 Watts RMS @ 2 Ohms
How do you find OHM?
Ohms can be found by using these formulas. Ohms = Volts/Amps, Ohms = (Volts (squared))/Watts, Ohms = Watts/(Amps (squared)).
How do you calculate watts?
The normal calculations for watts are as follows.amps x volts = wattsvolts2 / ohms = wattsamps2 x ohms = wattsScroll down to the Related links and look at "Watts, Volts, Amperes, and Ohms".
If an amplifier has an output of 350 watts rms 8 ohms what is the output at 4 ohms?
There is no amplifier with an output impedance of 8 ohms or 4 ohms on the market. All audio amplifiers really have an output impedance of less than 0.1 ohms. Scroll down to related links and look at "Amplifiers, loudspeakers and ohms"
How do you figure watts for 8 Ohm speakers?
The power rating of speakers has nothing specific to do with ohms. look at the Watts rating printed somewhere on the speakers
If you have two 150 RMS watt subs on the same ch of an amp What is the RMS watts needed from the amp?
Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms. 8 Ohms is not a problem load-wise for the amp, but if it is rated at 100 watts into 4 Ohms, then you will only get 50 watts into 8. Many car subs nowadays will handle a 2-Ohm load, but some will not. Your two speakers will handle 2x150 watts or 300 watts. An amp that is rated to drive 300 watts into 4 ohms will either deliver more like 500 watts into 2 Ohms, or it will melt through the floor of your car. So you need to look up the specs for your amp in the instruction manual. If it will only run into a 4-Ohm load, you can only use one 4-Ohm sub per channel. If it will handle a 2-Ohm load, you will have to turn it up slowly or you will blow your speakers out. Mr Ohm and his law will not be denied.
If a speaker is rated at 200 watts RMS at 8 ohms what is a good wattage to run to it?
it would depend on what brand and what size sub it is i would recommend 250 watts
How many watts to you need to have four speakers at 8 ohms each?
It depends on the power rating of the speakers. There is insufficient information in the question to properly answer it. Please restate the question.
How do you work out the current?
There are three formulas that you can use. Amps = Volts/Ohms Amps = Watts/Volts Amps = sq root of Watts/Ohms
