I'm liking it. I'm taking it easy on it right now cause I'm still getting to know it and get a feel for how much power it can take, it gets loud enough to satisfy me, but what's really nice is the sq on it. It sounds good on all types of music and is really tight and accurate, and doesn't sound muddy at all.
As far as what I've ran in the past, lol let me think, mofos, type rs, Fi BL, RE SX's, Solo X, and all kinds of other cheap prefab stuff. As you can probably tell most of my setups have been "loud" oriented so this is my first time switching to something geared towards quality sound.
I think it was a good decision since I'm tired of constantly wanting to "upgrade" to something louder and I also really like how this sub doesn't put a strain on my electrical system. To summarize: gets loud enough to satisfy while sounding great doing it. For the money the icon is a tough one to beat!
