If I want to power a set of Infinity components speakers, two 6 1/2" woofers with matching tweeters, that are rated at 110 watts RMS with 400 watts max capacity, how much amp power is recommended? I am considering using the Kenwood KAC-7201 and the speakers are Infinity Perfect 6.1 component system. Is this too much amp or too little and what about the quality of Kenwood amps?

Thanks for your input.

That amp should be okay as long as you run it slightly less than full power. The Infinity's should be able to handle a little more than 110RMS if you have them crossed over at around 100.

Thats a dangerous suggestion to make, "as long as you run it slightly less than full power". How about you just run it the way its suposed to be done and match your input sensitivity to the head unit output, the way its suposed to be done. The Gain is not a volume control, if it was it would say "volume Control" not Gain.

Ravendarat,

Can you please explain what you mean by input sensitivity?

Raven...I guess what I wrote was taken the wrong way. I never said a word about using the gain knob as a volume control. I suppose I should have said something more along the lines of...that amp will work just fine as long as you don't turn the volume on the HU to 30 out of 30 after you match the sensitivity of the amp to the HU.

See ,that sounds better, the reason why I took it that way is because what was written was "That amp should be okay as long as you run it slightly less than full power" with it implying the amp and nothing said about the head unit. No Harm no foul but when giving advise to people who are new and wouldnt know better you have to make things clear to avoid contributing to problems they might have. With that being said I have done similar things on this forum so its no big deal

You guys are awesome, I love this website! Your advice is greatly appreciated. Now after reading the article that DYohn sent to me I have to figure out what the Pre Amp output power of the Alpine-9833 should be. The specification in the owners manual says The Maximum Pre-Output Voltage is 4 V / 10 k ohms. Is this the Pre-Amp voltage signal?

Yes, that would be the maximum output signal level.
