Has anyone owned any of these? I'm interested in buying 2, but I need other people's opinions. I don't want to buy junk. I have a 2000rms alpine amp to push these in an SUV. So airspace and wattage shouldn't be a problem. I just really want to know if these subs will get down in a pretty much daily basis. And I greatly appreciate all of your opinions good or bad. I haven't been into car audio for a couple years. And as you all know, they come out with new stuff daily. Thanks for anyone that can help me out.
