You need:
a) Test tone cd (shoot me a pm if you need it)
b) DMM with AC Voltage setting
c) formula: voltage= SQRT (P x R)
- use a 50Hz or 60 Hz tone ( DMM must be calibrated to this)
- max RMS PWR of the amp multiplied with the speakers resistor and take the root of the result. The result is the max. voltage at peak power.
turn up gain until you reach peak voltage as calculated.
Or a bit lower to have a safety margin.
you are done.

hehe that was fun.
anyhoo for the other guys who arent crazy at math
if you have 300 watts of power (RMS) at 2 ohms comming from your amp and your subs are wired up at 2ohms resistance
then V = SQRT(300watts X 2 ohms)
so you get V= SQRT ( 600)
so your voltage should be 24.5V
