Line out converter voltage

I just installed a pac-2 loc in my sons s10 yeaterday. Does anyone know what the preout voltage is on these things? I have it hooked up to a memphis 16-mc300 which powers some boston 6.53. I know the factory deck isn't much but trying to set the amp gain doesn't seem right. I played with the gain and have it set on 5v. Anything else way off. Will the loc voltage vary with the volume level or will it remain constant?

setting amp gain to 5V implies that the LOC is putting out too high of a line voltage. Does the LOC you're using have it's own level or gain adjustment? If so, try turning it down some.
The best way to set this is with a tone generator or test tone CD, and an oscilloscope, but you can check basic pre-out voltages using an AC Voltage digital multi-meter.
