Wow...sorry I posted in haste without reading till the end of this thread
I don't have a M20, but I would expect that the sub out RCA will have variable volume output. Have you set this volume to max.
What crossover are you using, the one inside the M20, or the physical Dail in the sub.
Sorry iam completely unfamiliar with the M20, so posting my above silly questions![]()
No problem

Have set my crossover to around 70 Hz in the sub (QB 12), the M20 does not have volume control for the sub out. Sub volume at around 60-70%.
