Need a 2 or 4 channel amp

[Lurius 10+ year member]

I finally decided on what speakers I am going with.. The rear speakers are 60rms and the fronts are 90 rms(Infinity 6010cs in front and some Infinity panel 4x6's for rear).

I need an amplifier to power these, I was hoping for about 150$ range for the amp.

if I were to find an amp that powered 75w to each channel can I decrease the output to the rear channels any way? I want to avoid overpowering the speakers but would like to stick with only one amp for the speakers.

Would it probably be better, if I cannot decrease output to the rear speakers, to go with a 60w rms/channel and just power the front speakers with 60?

Any and all advice is welcome, open to recomendations.

Yes, you can attenuate the output for the rear speakers with conservative gain settings.

If at all interested (though possibly it isnt quite as much amp as you were looking for) I have a 4ch Kenwood KAC-846 (50w X 4 or 150w X 2 bridged) I'm looking to get rid of - have a look in my For Sale thread [link in signature] if you like.

RMS Power (at 12V,20Hz-20kHz)

-Bridged 4 ohms : 100W x 2 (0.3% THD)

-Per channel into 2 ohms : 50W x 4 (0.3% THD)

-Per channel into 4 ohms : 40W x 4 (0.08% THD)

2nd that. I bought a 400watt profile mono amp from a guy a few years ago and I just not got rid of it. Worked perfectly the whole time I had it and held its own against some amps that cost about $300 more. Not bad amps at all. I would expect the same quality from the 2-channel or 4-channel amps.

wow..scared me at 10% THD, but it's actually a much better .08% //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
