ok I got a friend with two of these and he is powering them with a 1200.1 I am not sure what his gains are set at but I know he is powering them with a 1200.1 and they are not the louidest but the sq is very nice and they also in an suv so in a civic they should be even louder not a bad sub but you could look into for like 120
Try an elemental K they can be had for 105$ a 15" if you preorder >//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif just ordered my 2 today heh
