I was told that the new Rockford 4 ch amp can only run 4 ohm speakers. I'm using Polk Audio 6x9 in my saddlebags they are 4 ohm. I'm using 6.5 inch Hertz speakers in the fairing they are 3 ohms. My question is will I do damage to the Rockford amp by using a 3 ohm speaker??? Thanks for any help given.

 

I was wondering the same.

 

the RF amp requires a 4 ohm impedance, running a speaker with a 3 ohm impedance may damage the amp, but you could always call RF and ask them?

 

Not likely to do any damage to the amp, but a buildup in heat is what you want to keep an eye out for. An impedence mismatch will cause a loss in sound quality, how much of a loss I don't know. I do know a difference between 4 and 8 ohm will sound like crap. So whatever distortion is created by this could possibily cause damage to the speakers at high volume.

 

So the heat is mostly the issue. I guess it warrants a call to RF. Thanks guys.

 

Hertz website reports the HCX 165 as 4 ohm. Refer to the attached picture.

I wanted to follow up on this thread.... Hopefully your still following it.
How did those 3ohm speakers work with that Fosgate Amp? I'm considering the same setup for my bike

 

I'm running 3 ohm on a 2 ohm oem set up....sounds all right , but I sacrificed low volume settings.......but the speakers are better sounding than the original crap. running a lower ohm speaker with a higher ohm amp will hurt one thing....the speaker.
