I am thinking hard on upgrading to this setup. My current one is a bit too loud. 100dB standing by the rear of the car at idle. (Drivers side, a few feet away).

I used this free program to record the volume.

So, I was wondering if you could record the db with the M+K setup at the above distance, as I really want it, but don;t want to go buy something that is louder than what I have. a recording at 6k rpm would also be great.

thanks for any help.
