Background, you are the man! I don't mean to hi-jack the thread, but it is relative to the original post. I hooked up the 2.5is to the d-sonic. those little old suckers have never sounded better...ever!!!. they can take a lot!!! I had to turn up the volume way up to really hear them the way they were intended. I have a newly found respect for those old things.. if only i'd kept the 3.3s. its also amazing what high power class d amps can do. but now I want the 4s, since you've said they're much, much better.
in the meantime, rock on everybody! thanks to everyone, especially background.
