The difference between 2 ohms and 4 ohms is 2 ohms.
2 in series with 3&4 in parallel
It is the impedence (coil resistence)normally sub component (drivers)are in 8 ohms impedence.2 in parralel is 4 ohms and 4 in parralel makes it 2 ohms.
That would yeild a 4 ohm load
Parallel
R = 1/[1/2 + 1/4 + 1/6 + 1/10] Add up the reciprocals of the resistances, and take the reciprocal of the answer.
Four 8 ohm speakers wired in parallel would give an effective 2 ohm load.
Yes, just make sure your amp can run at 2 ohms and you're fine.
the impedance of a speaker is a characteristic that is has. A 4 ohm speaker will always have a 4 ohm impedance and it cannot be changed. If 2 speakers of 4 ohm impedance are wired in parallel, then the total impedance will be 2 ohms. Similarly, if you wire 4 speakers together, the total impedance will be 1 ohm. Wiring a 2 ohm speaker to an amplifier rated to drive a 1 ohm load should work without any problems but expect the total power output to be somewhat lower than with a 1 ohm load.
You could go with a 600 watt 2 ch amp or a 300 watt mono block amp, depends on what OHM the subs are, if they are 8 ohm you could wire them down to 4 ohm or if they 4 ohm u could wire them to 2 ohm, i have a 600.1 Boss amp and subs are wired together at 2 ohm and they BANG.
nope
If you replace a 2 ohm speaker with a 4 ohm speaker you will only get one half the original power. This is usually not a problem because you rarely, if ever, run a stereo system at full power. Half power is only -3db, which is generally only one click on the volume control. It might also sound slightly different because the cross-over frequency might be different,
Yes, you can have a 2 ohm subwoofer and a 4 ohm subwoofer in the same system. However, it is important to match the impedance to avoid damaging your amplifier. You can wire them in series or parallel to achieve a compatible overall impedance for your amplifier.
