Can you use 4 ohms speakers and 8 ohm speakers on the same amp?

The short answer is yes, the long answer is maybe. Example: my Toyota's stock CD player says on it specifically, ''4 ohm speakers'', the stock speakers, however, say they are 6 ohms and they measured on a volt meter at 6 ohms. Certain higher end car audio speakers are 2 ohms but are designed for 4 ohm head units and 4 ohm head units can power 2 ohm car speakers.
4 ohm and 8 ohm speakers will work, however, different ohms can (but not always) cause different volumes out of each respective speaker. If your equipment if really old or really crappy it might get fried or if it is modern and of good quality it might get fried if you run the amp at the higher end of its output (high volume).
Short answer, you will be fine just don't ask the amp to work super hard.
Medium answer, I wouldn't bet more than a few hundred bucks of audio equipment on it and don't stress the amp. Long answer, its complicated and always best to match ohms even though the ohm rating is an average and 4 ohm speakers can present ohm loads of way less than 4 to over 10 depending on their output at the time.
Also if you ask different people you'll get different answers.

What ohms am i running if i have two 4 ohm speakers hooked up to my amp vs two 2 ohm speakers?
Don't know how you have subs wired but should be 4 ohm load is what your amp will see.
Can you put 4 ohms into 16?
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.
If two four ohm single voice coil subs are wired in parallel how many ohms will be on the amp?
Two four ohm speakers in parallel is two ohms. Make sure the amp is rated for that load impedance, or you could damage it.
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.
My speakers are 300w peak power with 8 ohm what amp is compatible?
There is no power amplifier with 8 Ohms output impedance. Therefore the usual impedance of this amp is arround 0.1 ohms which is good for bridging your 8 Ohm speakers. Scroll down to related links and look at "Interconnection of two units - Voltage Bridging - Zout < Zin".
If you have two 150 RMS watt subs on the same ch of an amp What is the RMS watts needed from the amp?
Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms. 8 Ohms is not a problem load-wise for the amp, but if it is rated at 100 watts into 4 Ohms, then you will only get 50 watts into 8. Many car subs nowadays will handle a 2-Ohm load, but some will not. Your two speakers will handle 2x150 watts or 300 watts. An amp that is rated to drive 300 watts into 4 ohms will either deliver more like 500 watts into 2 Ohms, or it will melt through the floor of your car. So you need to look up the specs for your amp in the instruction manual. If it will only run into a 4-Ohm load, you can only use one 4-Ohm sub per channel. If it will handle a 2-Ohm load, you will have to turn it up slowly or you will blow your speakers out. Mr Ohm and his law will not be denied.
Can 270 watt speakers damage a 125 watt amp?
Not unless the speakers are rated at a resistance (ohms) that is incompatible with the amp. Speakers don't generate power, the rating only tells you how much they can handle. So, speakers capable of up to 270 watts, can certainly handle 125 watts. However, if the amp is not 1-ohm stable and the speakers are 1-ohm, you could cause the amp to cut out and overheat depending on the protection mechanism of the amp.
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.
What is better 16 ohms speakers or 8 ohms speakers?
It depends on the application. If you have an amp that is stable in 8 ohms per channel, then 8 ohm speakers will work best. However, if you wanted multiple speakers on that channel you could use two 16 ohm speakers.
Do the ohms on speakers have to match the ohms of the amp?
In fact there is no "8 ohm output" on an audio power amplifier and no Zout = Zin. In audio technology voltage bridging is the normal connection method where Zout < Zin. Read the link: "8 Ohm Output" and "150 Ohm Input" - What is that?
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.
Can you wire 2 16 ohm speakers to 16 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.
