Can you put 2 8 ohm speakers together?
Two 8 Ohm speakers wired (hooked up) in Parallel results in a 4 Ohm load. It's easy to calculate the effect of a resistive load when all the speakers are all the same resistance. It is really not suggested to wire different resistive load values in Parallel (8 and 4, 16 and 8 etc.)
What is the maximum number of 8 ohm loudspeakers you can safely connect in a parallel configuration to an amplifier channel with an impedance rating of 2 ohms?
You can connect four 8 ohm speakers in parallel to match 2 ohms. Or as many as you want in series/parallel. But whether they will be loud enough depends on the amplifier watts and the loudness you need from each one.
How many 8 ohm speakers in parallel?
The formula for figuring the total impedance in Parallel is the multiplication of the two loads divided by the sum of the two loads - i.e. putting two 8 ohm speakers in Parallel results in a 4 ohm load.
How do you hook up 4 8 ohm speakers?
Connect the two speakers in parallel to one another. Two 8 ohm speakers in parallel to one another would have an impedance of 4 ohms. Now connect the two groups of these speakers in SERIES. So now you have four 8 ohm speakers connected in a way, that their combined impedance is 8 ohms.
