pretty loud actually for daily.youre probably in the 130's with the r's sealed

probably low 130's unless i have hearing loss. It isn't impressive loud, but it shakes shit a little bit.

i have a modified prefab with the help of RE_CALCULATOR,and to be honest,i couldnt take another cvx in my hatch.clean and loud ! i would allso agree,if the guy put 1/0 wire and a box that was 2.2-2.4 cubes per sub,face em towards the back.his fender might fall off.but he would blow those rrrrrr'sssss away
