[quote=rcmatt I do agree the bevel box whines a lot, but that may be in part that it is right behind the seat and there is a lot of "body" to keep the sound in.
That could be the case, but I don't think it is, as some BB's are quiet but most are not. If you have a noisy one, then as it is practically in the car with you, it will be heard.
My first M3W had a BB that was as quiet as the grave, the 2nd one sounded like the devil was having a party around the grave, especially if, as has been said, it was up to temperature, say after half an hours main road running.
