I love to feel it too! But here's what is going on. As you reach distortion levels (dc on the outputs) because your amp is clipping, you feel it more. So as has been said a few times already, your amp isn't powerful enough for what you want to do, and as you crank it up, you are putting distortion out which in this case is clipping which your speakers see as DC = Blown drivers.
You can feel it a lot without distortion but you will have to pony up with a big high current amp and some capable speakers. Just keep in mind that although 160 watts per channel seems like a lot, it really isn't all that much. My Bose 1801 can put out up to 400 watts into my Kef 105s. Do I ever push it to 12+? No, I don't want to blow my eardrums.
Good clean power is deceptive because it is loud, but there's no distortion, so you think you need to turn it up more.
Put on Avril Lavigne's Sk8tr Boi, and I guarantee you will feel it, if your equipment is capable.
