I am running an IDQ12v3 in my truck and this thing is just flatout amazing regardless of what you want to listen to...Granted it is a little over budget, but man what a sub. It blends so effortlessly with the front stage that it doesn't draw any attention to itself, and can make an average install/tune still sound great. Also, its ability to play very well and accurate up to 100hz really bring rock music to life if you aren't running dedicated midbass drivers....In contrast, the 13Ov2 I am running in my S10 is not nearly as good above 65hz or so...I can adjust the Xover from 70 to 250hz and barely hear any difference because of its natural roll off in a 1.0 cf sealed box.
Another great option would be the ID12v3, another fantastic sub but $100 less than the IDQ...there are several people who believe this driver to be almost as good as the IDQ on the forums...
I listen to a lot of older Tool, Deftones, Sevendust, etc. and the IDQ has done everything I have asked of it and more...I keep getting out more old CDs that I never could get the bass right on with previous subwoofers, and it just nails them all without even adjusting anything. Seems like with all my other subs I would have to adjust something for each new cd. This sub makes it so easy, it is like it is self-adjusting... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
