Finally received my 12" SP4 subwoofer! Just now getting into car audio and after some research this is the sub I ended up deciding to go along with my SQ2200 amp. Being new to car audio I have nothing to compare it to but it feels and looks like a very solid well built subwoofer. I'm excited to hear how it sounds as it loosens up once broken in a bit. I have it in a 2.75 cu box tuned roughly to 31 hz and it sounds pretty good right now based solely on what I think I'm expecting it to sound like.
