I would appreciate any advice on helping me with this issue. As many of us know, the stock speakers were inadequate so I ended up replacing them out. I didn't have alot of money to spend so I purchased relatively inexpensive speakers. Other than the replacement speakers the system is stock.
Now the problem. Iv'e notice in my dash speakers (Inifinty brand Kappa something and only these speakers) a buzzing sound that occurs mainly on AM talk radio. The buzzing sound is similar to having a piece of something that has dropped and is bouncing on the cone. It only makes the buzzing at certain frequencies (?). For instance, a conversation is being broadcast and only one of the announcer's voice makes it buzz. I learned to live with it until now when I listen to my Radiohead CD. This really creates the buzzing sensation. Any ideas or solutions? Thank you.
Randy

im having a similar problem ... from what i can figure out an amp is going to take care of it stock head unit is not powerful enough to power thew new speakers

That is usually the case with aftermarket speakers. It seems the better they are, the more power it takes to drive them at the normal level. Ron

You guys are talking about what is called "the sensitivity" of the driver. The higher the sensitivity, the more volume is produced for the same input. It's measured in sound pressure level per watt at 1 meter. This is one of the factors that has to be matched properly in a multi-driver system. Just buying expensive speakers does not mean they will sound good.
The OP mentioned a buzzing sound. I have seen (heard) this when dirt gets into the spider and when the baskets are warped from being installed on non-flat surfaces.
It might also happen if you drive the amp into clipping (this chops the tops off the wave patterns when the output stage is overdriven). Thought usually this is sort of a popping sound, it's hard to describe. A bad impedence mismatch between the driver and the amp can aggravate this.
If you can hook up the drivers to a different HU, you can at least see where the problem is.
I know this didn't really go anywhere, but hope it helps..

Could have something to do with the head unit's amps being spec'd for 4 ohm speakers and the kappas are 2 ohm speakers. You could be overloading the head unit's output amplifiers.
Or you could have defective speakers. (Are Infinitys now made in China?) If you have a woofer voice-coil interference problem, you should be able to manually press on the woofer with 2 fingers, one on each side, for balance, and you should be able to move the woofer cone in and out without feeling any voice coil rubbing. But if you feel rubbing, this will be audible when playing sound through the speaker.
As you push (lightly), you'll get a sense of whether the voice coil is maybe off center, by changing the way you push, push slightly harder on one side relative to the other, and if that works better (eliminates the rubbing), your woofer's voice coil is off center relative to the woofer cone. If it's off center, its a defective speaker. Happens more than you'd think.
My 3.5" dash kappas ended up hissing\crackling because my buddy had wired them up incorrectly (note that the wires are NOT color-coded) all you do is switch the ones that can be around, and it'll work fine. Then again, I'm not underpowering them. I have my rear pass kappas, and door kappas all powered by a PDX 4.100 amplifier, so my D3 is ONLY powering the dash kappas...if you are underpowering them, then weird noise can come along.
