Never experienced this problem.

NOTE: My implementation is such that I keep the empeg at 0db and control all volume-related issues and equalisation from a Sony head unit (to which the empeg is connected as an aux device) in the car; at home I connect to a tuner and control volume from it (i.e. NOT from the empeg).
