Testing Head Unit output signal on "quiet" non-Navi '05
Just checked the HU output through the 20 pin connector that plugs into the factory amp. My factory non-navi 2005 system is barely audible at full volume when it's cold out.
Both left and right channels showing 0.12 V on my multimeter (set to max 2 V AC) on max volume when playing a 1kHz test tone. I should be seeing 0.8-1.0 on max volume, correct, the measured voltage is simply the amplitude of the sine wave on the test tone?
Can anyone confirm my HU is FUBAR, or is there something I screwed up on the measurement?
