Need help with strange gain knob

2 dvc 4 ohm subs can't be wired to 2 ohms. It'll be either 4 or 1 ohm depending on how you wire them. That changes the voltage calculation.

Search "test tones" on this forum you'll find ways to make your own test CD. You want the level to be recorded at 0dB so it's the same as commercial music CD's. You can't use music cuz it won't give a steady reading.
