I have an Alpine MRP-F200. It's 4x75W (300W). I'm not really that much of an amp expert, but it's good. It was the cheapest 'nice amp' that the place that did my empeg install had, and was only a little bit more than some good deals I found online. I took the easy way. It gets very loud, and the sound is clean. More than that, I can't say.
