My IDQ 12 was stolen from my car, looking for an equivalent replacement. Power will be via MB Quart ONX 1.1500D (750RMS at 2ohms). Tight bass response is more important than overall loudness (although I do like to blast occasional house/dubstep). Definitely want a sealed enclosure for that reason. My favorite part about the IDQ was the clarity and musicality no matter what I was listening to. I'm open to going with two 10s if someone has a good option. Let me know what you've got.
