You will find no 4 ohm amplifier! So you will need no transformer. All audio amplifiers have output impedances of lower than 0.5 ohms. We have "impedance bridging" between amplifier and loudspeaker - no matching. Scroll down to related links and look at "impedance bridging - Wikipedia".
What else can I help you with?
Can a 4 ohm bridged car amp handle a 2 ohm speaker with proper amp cooling?
nope
Can you connect a 8 ohm speaker for a amp designed for a 4 ohm load?
You can, but the available power will only be about half of rated, and the frequency response will be slightly different. Better would be to connect two 8 ohm speakers in parallel, making an equivalent 4 ohm speaker.
Can you run 4ohm resistor to make 4 ohms speakers 2 ohm?
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.
Can you use a 8 ohm 400 watt speaker on a 4 ohm 350 watt amp to play bass?
Yes, you can use an 8-ohm 400-watt speaker with a 4-ohm 350-watt amplifier to play bass. The speaker will receive less power from the amp, resulting in lower volume, but it won't damage the speaker or the amplifier. Just ensure that the overall impedance of your setup matches the amplifier's specifications to prevent any potential issues.
Can you put an 8 ohm resistor in parallel with an 8 ohm speaker to make your amp think there is a 4 ohm speaker conected and if so will it change the sound or frequency?
Why should an amplifier think it is better to have a heavier load? Use the 8 ohm speaker. If your amp has a 4-ohm output you can strap a pair of 8-ohm speakers in parallel across it to match impedances. When impedance is matched to the amp, maximum power transfer happens. A mismatch doesn't let maximum power get transferred. The sound of speakers that are matched in impedance with the amp will be the same as the sound of mismatched speakers at low power. At high power (high volume), you can end up with some problems. Talk to your local audio guy and get up to speed. Take a couple of cold drinks into the store when things are not busy, hook up the audio person with a beverage, and then open your ears and pay attention. You'll learn a lot.
Will 8 ohm sub woofers work with a 4 ohm amp?
if you put 2, 8 ohm speakers together on the same channel you will trick the amp into seeing a 4 ohm load, it is not advisable to run a 8 ohm coiled speaker on a 4 ohm amp unless you do the above. So if you want to run 2 8 ohm speakers from a 4 ohm amp this will work the best although the amp will need to be hefty as its worse to underpower a sub than overpower it! I have used a 8 ohm speaker myself on a car amp and had no problems but it was not a cheap entry level amp! some amps will take it, others will get hot and enter protection mode. Hope this helps!!!
Can you replace an 8 ohm speaker with a 4 ohm speaker?
Only if your amplifier is capable of driving a 4 ohm speaker. Some have a switch on the back to select 4 or 8ohm speakers. Details should either be printed some where on the back of the amp or the instruction manual
If an amp runs 1000 w rms at 1ohm how do you wire a dual 4 ohm speaker to run at 1 ohm?
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.
1994 explorer with jbl system the rear sub speaker is blown can you buy a another 8in jbl speaker and wire it to the rear amp and put in a box if so what ohm should the speaker be?
yeah it dont matter the ohms as long as its 2-4 ohms and u should be safe cause the amp will auto ajust to 2 ohm or 4 ohm...............good luck but u wont have the power to push it .....try it and if it dosent have power to push it ad an mtx amp This is a special JBL speaker for the Ford/JBL system. You can have it repaired for around $40 at www.simplyspeakers.com. Call 1-800-511-3343. Servcie takes about 1 week and it will perform just like new!
Can you power 8 ohm speakers with a 4 ohm amplifier?
Yes, but you won't get rated pwer. Best is to match the speaker to the amplifier.
Can a 1 ohm auto speaker be replaced with a 4 ohm auto speaker?
Yes It can be. But can your amp handle a 1 ohm load? you can go to this web site www.the12volt.com They have load calculator's and also you can ask the car audio gods any questions and the will answer all you questions for FREE....
What is 6ohm in amps?
Ohms is a measurement of resistance between the amp and speakers. Most home audio is 8 ohm, if you run 4 or 6 ohm speakers you cut resistance down and get more power out of the amp. Say your stereo is 100X2 @ 8ohm, if you use 4 ohm speakers you should get 50% more power BUT the amp is working twice as hard and can burn up.
