Anybody that can help me with this? They are both about the same price. Going to be running two of them off a Soundstream 2000d So they'll be ran at 1 ohm. I know the XFL's have a .5" bigger coil and are rated at 1000 rms whereas the Sundowns are rated at 600 but i know both of these subs will take more than rated. Could the sundowns take 1000 rms daily? I have heard lots of good things about them both so im wondering if anyone could offer advice from experience.
