Is there anyway I can measure the gain on my speakers in the front (6.5" comps) and rear (6.5" comps)? They are driven by separate amps. Of course, I want them to be equal (the same loudness). I could probably use my ear but that's hard. Do I use a multi-meter?
put a dmm in the speaker leads of the amp on ac voltage as long as your getting the same voltage to both speakers your gains are set correctly for both amps.
