No. You can get way louder if you do it yourself for $400 And that can include wiring and an extra batt. If you're open to some suggestions lemme know.
the aq 2.0 compares in no way to the crossfire c5 maybe the aq 2.5. but yes i would get an aq 2.5 tomorrow its 139 plus shipping usually. you can get it for 15 percent off and free shipping.
id rather order a skar 12 with custom box for 199 than the crossfire. great subs that get low. much beefier than the c5 and then you get a d2 and buy a mono block
