I agree with the Crescendo 3500 recommendation as well. When it comes to powering subs and daily systems I tend to recommend hovering somewhere around RMS rating as well but I'm of the opinion that there's no such thing as underpowering a sub either. I would imagine that even 1.5 or 2kw would even yield more than suitable results, at least for myself. Of course I wouldn't likely be able to resist giving that beast a 3500 either if I was to spend the money on one, lol. Your first post didn't include a great deal of information and quite frankly mimicked many of the newblet posts we see. It is kinda hard not to be a bit of a smart ass when someone who has no business using a sub like that and who probably wouldn't ever actually buy said sub anyway asks a question like that because as Jon said, it's a loaded one. Seeing as how you're no newblet and appear to have a working brain with a grasp on how to use it the best thing to have done would have been to start with some of what you posted in the #8 post along with your actual goals and what you were really asking and wanting to know. I am certain that aside from a little kiddin around you would have gotten the answers you had expected. You became a member on this forum for the same reason that pretty much all of us joined and love this forum for. Despite a few smart remarks don't get discouraged, these are a bunch of really good guys whose combined knowledge and experience is second to none. I hope you continue to enjoy the forum and take the smart assin' as a little bit of new member hazing, lol. Welcome to the forum John, you're about to buy and use some world class equipment.
