hey i decided to measure the subwoofer pre-out voltage on my ALPINE 7995 after reading this thread http://www.caraudio.com/vb/showthread.php?t=102017 .

I did the following playing a 0db 50hz sine wave:

-when i had the volume at 25 (out of 35) and the subwoofer level at +15 (out of 15) it measured a little less than a volt!

-when i had the volume at 30 (out of 35) and the subwoofer level at +15 (out of 15) it measured a little under 2 volts.. about 1.8 volts

-when i had the volume at 35 (out of 35) and the subwoofer level at +15 (out of 15) it measured a little under 4 volts.. about 3.7 volts.

i currently have the gains on my amps set at VOLUME 25 being the max.. what im wondering is should i be setting the gains at a little higher volume, now that i know that the HU puts out LESS THAN A VOLT at volume 25??
