DMM gain setting questions

[explorer2 10+ year member]

What do you do when you get more voltage than you should be with the gains all the way down, processing off, levels at 0? I didnt have my o scope handy so I just used my meter to get things working and following the instructions with the sub level turned up I was getting more than double the specified voltage (almost 45 VAC) with the gains at zero, turning the sub level down to 0 still got me more than spec(25 VAC). This is on a jbl gts300 and an idq10 d4. Its rated at 100x2 @ 4 which is how its wired, I guess that this means that it is pretty underated.

It probably means you have too much preout voltage going into your amplifier. You really need to get your scope out to see what is really going on.
