were talking RMS, the ranger back windows are known to not like it, as i can not tell if he has a slider in the back or not, i had 1500 RMS system in the back of my old ranger, i blew that out the first time the bass hit hard with the windows up....
FWIW, 1500 RMS on some kcikers is well over 3k peak, prolly more near 4k. and cars can do it becuase the side windows are not rigid mount and the back and front glass have a curvature to them which doesnt allow the frequency to resonate in the glass, if u have a slider rear window u should be fine, if u dont.....bye bye glass
