I used to run USD Millenium Y-210's in my Scion... these are the *ish* if you want smooth SQ. I had 4 of these 10" subs in 3.2 ft3 with an A-Periodic matt all put into a custom inclosure with FG, Plexi, and 50 LEDs...ppl and judges used to think it looked too pretty to perform, but it blew ppl's minds as to how crisp and clean they were (never judge a book, by its cover ppl!). //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I no longer have the xB anymore... oh well, onto more challenging projects!
