It must have a driver going bad. When you changed channels with your speakers, and the problem changed channels, you proved the problem is in the speaker.

With that low power of an amp, it would easily saturate at high output levels. When an amp saturates (clips), it has nearly a DC output that can quickly fry a speaker voice coil that's rated at much higher power levels. It can also cause the voice coil to separate from the cone, resulting in a buzzy or raspy sound at high volume levels, particularly with the bass. When you swapped out the speaker from one output to another and still had the problem, this indicates that the problem is in the speaker and not the electronics driving it. I would say that you have a blown woofer that needs to be replaced. The good news? Cheap speakers are cheap to repair. I concur with Magyver.
