Lightbulb Can you use 4ohm & 8ohm speakers together

I'm in the process of upgrading my front door speakers as I have infinity kappa on there now...my rears are midrage 4ohm and the speakers I want for the front are 8ohm ...can I use them with my 2channel amp? Rears on one channel and fronts on the other?

Right now I don't have that problem as they all are 4ohm....

It will work, the 8ohm speakers will see less power

I understand that part...I just want to be sure it can work together being hooked up to the same amplifier...that is a 2channel

Thanks

The impedance isn't the real issue I see here.
How are you planning to power a pair of of L and R channels off ONE channel and manage front and rear?

If you are planning to do what I think you are, it won't work.

We need a little more information to give you an accurate answer. Which amp are you using and how do you currently have your speakers wired to it?

If you do the front speakers on 1-channel and rear speakers on 1-channel, if will technically work (meaning the amp will not go into protect) but you will not have stereo and it would sound very poor.

Stop !!!!

If your using a passive crossover the coils will only be 1/2 of what you need, so if you have a series c/o you'll cook the tweeter.

the difference between 4/8 ohm coils for 2400hz .512mh & 1.06 for 8 ohm. So in thoery 2400hz will be 1200hz. this is on a 12db 2nd order.
