What is the experts opinion on using either the Crossfire Infinity amp. Or the one built into my Kenwood DNX893S, thanks for any help on this matter.
I am using the built in Kenwood one at the moment as it is easier to wire up than using the Kenwood pre outs.

 

Well, wait. So you are driving the speakers directly with the head unit?



That's what I'm doing with my SE, but that car never had an amp so it was set up that way.

 

That is what I am doing.
Good sound quality is of no use to me as I am using hearing aids but l would like it to sound the best for any passengers, especially my picky son.

 

At 22 watts per channel, it's not a lot of power, but the audio will be clean and good. For my use, my JVC head wired to the four door speakers and two added-by-me rear speakers is adequate - and it sounds wonderful.



I once knew the power rating of the OEM amp, I want to say 70 watts per channel, but one channel drives the left door and rear speaker and the other channel drives the other side. SO that's 140 watts total. Your head will do 88 watts total. That is not even twice the power, which to the human ear is 3dB so again, I think you may find that use of the amp is not all that helpful.

 

Crossfire specifications say 240 Watts
