Just figured I'd make a post about how I fell in love with my new dd-1. lol. I just got it in the mail today and on my lunch break, I tuned my hdc3 18's which are runnin off a crescendo bc3500. I gotta say, holy shit! It sounds incredible. The subs are still in their break in period and at 15 out of 40 volume, my windshield is flexing like no other! Only downside is, now i need to amplify my mids/highs! Thanks again Steve! 2 thumbs way up on the dd-1!
