Need help setting gain

[OllieCollie]

I only use Spotify to listen to music and I used a 40 Hz test tone and use the multimeter to set the voltage to 27v ac (28.28v ac is the spec) but when looking at the voltage for some songs it will jump around and peaking around 35v ac. Is this okay/normal? Is it just getting peak power and is fine rms wise? Is there a better way to do this? Just don't want to ruin my sub. Thank you in advance!

Should be fine. You are just seeing impedance rise from the sub playing.

I don't have the sub hooked up I'm testing across the speaker wires

It is ok. Music is dynamic, so you will have peaks and valleys. Subwoofer RMS is what it can play constantly with no issue. Maximum is what it can handle in bursts without issue.

So to be sure, if I use the test tone and tune it to the required voltage there's no risk for any damage?

No risk at all.
