Ok, i'm searching but getting mixed signals. What's the difference between the IDv3 subs and the IDQv3? I picked up an ID12V3 brand new but before i use it should i get an IDQ? Putting together an SQ based system. Not looking for volume, a single 12 is more than enough for me. Also, its going in about .9 cubes and i have 400 watts at 2 ohms. This is one of 3 subs i'm testing for permanent sub duty so i want it to be good lol. Thanks!
