I have a Kenwood 728s 2 ch amp, pair Infinity Kappa 6x9, pair of Infinity Ref 6 1/2 speakers. I had planned to run them in parallel but just found out there would be frequency cancellation. What is this and is there another way they can be wired to the amp for max power?

Frequency cancellation?  Who told you something like that?  Assuming your speakers are 4 ohms and your amp is 2-ohm stereo stable, you could connect them in parallel if you want to.

It is 2 ohm stable, I'm very new to car stereo and I've learned alot from this site. I saw the frequency cancellation bit from a different question in the forum.

More than likely you were reading about using different size subs when dealing with frequency cancellation, not internal component or coaxial speakers.

You can use that amp to run all 4 internal speakers like DYohn said, but here's what you will run into...

You can wire the front (2) speakers to one channel, and the rear (2) speakers to the other. You will retain Fade control (front and back), but you lose Balance control (you will not have a seperate left/right signal).

Or you could wire the front and rear left speakers to one channel, and the right front and rear speakers to the other. You will retain Balance control (left and right), but you lose Fade control (front and back).

That amp is not a good choice to run 4 internal speakers. Your best choice for that application would be either (2) 2-channel amps (one for the front speakers and one for the rear speakers), or (1) 4-channel amp.

I currently have (2) Kenwood KAC-649s amps running my Infinity Kappa's.
