    I'm looking at replacing my stock speakers with some Kenwood Excelon models and noticed they carry a 3 ohm impedance. I've never actually wired 3 0hm speakers to an amp and most amp specs provide 2 ohm and 4 ohm load ratings. Can anyone tell me whether wiring these speakers to this amp would impact the power rating? Thanks in advance!

    I wondered if it would put out between 50 and 75 watts. Thanks!

    how did you determin they were 3 ohm speakers? all 4 ohm speakers will measure DC resistance at about 3 ohms, and in addition to that even 4 ohm speakers never reach 4 ohms unless they are played at their resonant frequency, 99% of the time speakers are presenting anywhere from 4-15 ohms to the amp depending on frequency.
    it will be just fine unless the amp is not capable of less than 4 ohm loads

    its a missprint, it says below that it is a 4 ohm system. the speaker may have a 3 ohm dc resistance however but there would be no real bennifit to having a lower impeadance speaker. it might be slightly louder than a 4 ohm driver if it is true but i think its a missprint

    I wondered if that's what it was.
