[QUOTE="FoxPro5, post: 5705808, member: 562649"] Your DMM's not reading watts. But that's kind of besides the point, here. Just take the loudest, most dynamic music track and put it on repeat. Turn your amp gains to minimum and crank you HU to 30-32 out of 35 (assuming the output is not linear and 35 is clipping). Add gain in small increments or have a friend slowly add a little until you're satisfied with the volume. Your HU preouts are rated at 4v MAX power. You won't get 4v until you're at 35/35 with a 0 dB tone playing. The RMS of a 0 dB tone is about -3 dB. Most modern music is about -10-12 RMS. Just threw that in there so you understand what's going on with playing tones and using your DMM. [/QUOTE]
