Sure, If you mean your stereo has 4 ohm output and using 16 ohm speakers. The volume will be reduced somewhat by doing this, but it won't harm the stereo. If you have 4 ohm speakers and stereo is designed for 16 ohms you can do it ,but the amp will run hot and you may suffer damage at high volume to the amp.
You can't. Two 4 ohm speakers in parallel equal 2 ohms, and two in series equal 8 ohms. It is possible to wire four 4 ohm speakers so that the load is 4 ohms though. Put two in series (8 ohms). put the other two in series (8 ohms). Then put the two sets in parallel (two 8 ohm sets in parallel equal 4 ohms).
To calculate the resistance in ohms, you also need to know the voltage. The formula to find the resistance in ohms is R = V^2 / P, where R is the resistance in ohms, V is the voltage, and P is the power in watts.
The Sony XM752X amplifier can output up to 280 watts RMS per channel at 4 ohms, or 380 watts RMS per channel at 2 ohms, when both channels are driven with a 20Hz - 20kHz signal.
You need some amplifiers.
It seems you mean a tera-ohm which is a million million.See related links below
16 Ohms. Yes 16 ohms in series. 4 ohms in parallel
There is no single standard. Many computer speakers are rated at 8 ohms while others are 16 ohms or higher. My computer subwoofer here is 4 ohms.
a) Put 2 of the resistors in series to make a 200 ohm resistor. Then put the 100, 100, and 200 ohm resistors in parallel for 40 ohms. b) Put 2 resistors in parallel for 50 ohms. Put the 50, 100, and 100 ohm resistors in series for 250 ohms. c) Put 2 resistors in parallel for 50 ohms. Repeat with other 2 resistors. Put the two 50 ohm resistors in series for 100 ohms. This configuration can withstand 4 times the wattage of each individual resistor.
The nominal 8 inch speaker impedance can be 4 ohms, 8 ohms or 16 ohms. It depends on the make of the loudspeaker not on the 8 inches.
0.016 k ohms can be stated as 16 ohms. This is because "k" stands for kilo, which is a factor of 1,000, so 0.016 k ohms is equivalent to 0.016 × 1,000 ohms. Therefore, 0.016 k ohms = 16 ohms.
If wired in parallel then 4 ohms.
No. Two 16 ohm speakers connected together are either 32 ohms, if wired in series, or 8 ohms, if wired in parallel. You can, however, connect four 16 ohm speakers in series-parallel to get 16 ohms, with four times the power handling capacity of just one.
The difference between 2 ohms and 4 ohms is 2 ohms.
The final impedance would be 4 ohms.
2 ohms of resistance
You can't. Two 4 ohm speakers in parallel equal 2 ohms, and two in series equal 8 ohms. It is possible to wire four 4 ohm speakers so that the load is 4 ohms though. Put two in series (8 ohms). put the other two in series (8 ohms). Then put the two sets in parallel (two 8 ohm sets in parallel equal 4 ohms).
Ohms is a measure of impedance (resistance), not volume.
