[QUOTE="squeak9798, post: 915809, member: 555320"] Yeah, that year Alpine was pretty famous for weak outputs; atleast on the subwoofer output. Also realize that, on that Alpine, the sub level has to be set to +15 for full output. Anyways; you'd grab a DMM and set it to volts AC, stick the DMM's red lead on the inside of the RCA preout, the black lead on the outter shield of the RCA preout, play a 0db sine wave and read what the display tells ya. Also keep in mind that, with only a DMM, you won't be able to monitor the point of clipping. I'm not sure if the Alpine's clip and at what volume they do (if they do). [/QUOTE]
