Yes, you can safely use a 4 ohm amp with one 8 ohm speaker, but you will not achieve full power.
The 4 ohm amp is designed to supply a certain voltage into a 4 ohm speaker. Supplying that same voltage to an 8 ohm speaker will result in half the power, or -3dB. For maximum power, use a 4 ohm speaker, or two 8 ohm speakers in parallel.

∙ 14y agoYes, you can replace 4 ohm speakers with 8 ohm speakers, but the available power will be less by 3 dB, or one half.
Wiki User
∙ 13y agoI'm not sure why you'd want to do that. If you wire two 8 ohm speakers in parallel you would reduce the resistance of the speakers to 4 ohms.

∙ 12y agoYes you need to add a 16 ohm resistor in paralell, just make sure it can handel the desired wattage.

A series circuit has individual resistor values of 200 ohms 86 ohms 91 ohms 180 ohms and 150 ohms What is the total resistance of the circuit?
In a series circuits, you simply add the the values of each resistor and that is you answer. i.e. - 200 + 86 + 91 + 180 + 150 = 707 ohms
Does an open resistor measure 0 ohms?
No, an open resistor has a value of infinity. An open resistor typically will measure over 900 Megohms. A zero ohm resistor is exactly that, and will measure zero ohms. They are typically surface-mount devices.
What is a fixed resistor measured in?
Resistance is measured in ohms.
What is the function of 240 ohms resistor?
To provide 240 ohms of resistance. What those 240 ohms do in an actual circuit depends on the intention of the designer.
How do you convert 8 ohms to 4 ohms?
wire two 8 ohm speakers in a parallel circuit!
How do you wire one 4ohm sub?
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).
Will speakers rated at 4 ohm work safely at 2ohm?
If the output plug require 2 ohms speaker and you will plug an 4 ohm speaker, will be safer for speaker but the sound will be not so loud. (Yes, and maybe no... Not knowing your exact setup ill speculate, Assuming your actually dropping the ohms of the speaker.....If you parallel the 4ohm speakers it will drop them to 2ohm. But this will also double your wattage output. That is where it can get dangerous. If your speakers are rated at 200 watts and your Amp is putting out say 200W at 4ohm, when you parallel the speakers and drop that down to 2ohm it will now be pushing 400W at 2ohm... and your speakers can/will be damaged. So check how many watts your going to be feeding your speakers when you drop the ohms down and as long as it doesn't exceed the wattage of your speakers you should be fine Now, If your just plugging a 4ohm speaker into a 2ohm slot. (As long as your wattage is fine) your speaker will be fine, Just possibly not as loud as an equal 2ohm speaker may be. )
Can I safely run 4 x 4ohm speakers with an 8 ohm rated amplifier?
Not really. The only possible configurations of four 4 ohm speakers is 1 ohm, 4 ohms, and 16 ohms. This will not match an 8 ohm rated amplifier. It will work, but you will not achieve rated power output, and you run the risk of damaging the amplifier.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
How do you determine shorted resistor?
A short circuit is an unexpected path of zero resistance between two nodes in a circuit. If you measure the resistance of a resistor, and find that is has zero ohms, but the resistor is supposed to be somthing else, such as 100 ohms, then you can conclude that the resistor is shorted. Keep in mind that the precision of the measurement might be critical. If the resistor is supposed to be 100 ohms, but you get zero ohms, then the answer is easy. If the resistor is 0.001 ohms, but you get zero ohms, then you have to consider the precision of the measurement, the resistance of the wires, etc.
What is resistor unit?
Ohms
Is the resistance value of the resistor 22000 ohms 22 megohm resistor?
22Kiloohm is 22,000 ohms 22megohm is 22,000,000 ohms Kilo is a thousand meg/mega is a million
How does one practically apply ohms to amplifier vs speakers?
the watts for 2 ohms is more than 4 ohms. depending on the ohms your speakers take up and the wattage the speakers use, tells you what size amp you need.
What is the value in ohms of a resistor colored yellow yellow red?
4400 Ohms
A series circuit has individual resistor values of 200 ohms 86 ohms 91 ohms 180 ohms and 150 ohms What is the total resistance of the circuit?
In a series circuits, you simply add the the values of each resistor and that is you answer. i.e. - 200 + 86 + 91 + 180 + 150 = 707 ohms
What ohms are there in replacement speakers for 2004 Nissan Xterra?
There are 4 ohms
Can you wire four eight ohm speakers to four ohms?
I presume you mean wired to four ohms amplifier output: In this case, pair the two speakers in in series which will make the give you 18 Ohms and then join the two pairs in parallel which will result in approximately eight ohms. Then connect then in that format to the amplifier. It will work for you.
