You'll love the D9...its a great amp and you can really abuse the hell out of it. I've been running mine at .25 for a few days on a SS-XXX15 for testing and it's totally stable for burps and stable on music almost full tilt. It really comes alive under 1 ohm //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
