I'm a little partial to AQ because I like the loudness of their subs for the price. I had 1 hdc3 12 on an AQ 2200 and it was insane. I loved it. I want to upgrade to 2 18s now and I was totally set on AQ hdc3s until a buddy of mine recommended fi q 18s and ssa icon 18s. I wanted to see if I could get on here and get some more opinions. I have a Chevy trailblazer. I'm running kk 1/0 wiring. 150 amp alt. (don't plan to upgrade right now). 1 AQ 2200 (will eventually upgrade to a 3500). I haven't measured out my box specs yet, but what subs would be best for LOUD spl but also sound good on rap music. I'm a young jeezy, Gucci mane, lil john, gorilla Zoe type of bass listener. This will be for everyday enjoyment. Any help would be greatly appreciated. Just let me know.
