I would follow the advice given by Ann. If that fails to come to a resolution then bring in someone else to talk to him with you again. If that fails to work bring it up at a business meeting. Please be kind and let the pastor know that you will bring it up at the meeting before hand. If none of that works and the music is left to loud it may serve you and your family to attend elsewhere.
However, the latter should be a last resort and only after all possible avenues have been met. Just know that sometimes even the best intentions and the kindest hearts are met with offense. Do your best and leave the rest to God.
You said a mouth full then Rev, you said a mouth full then.
