Installation

Set your source volume at 1/2 to 3/4 volume and leave it. Always use your volume as a master (main) volume control. It has better electronics, a higher S/N ratio, and is more linear than any source unit volume available. If engine noise is audible, raise the volume on the source unit and/or check the ground connection on the unit.MEMPHIS AUDIO EQL7 7 Band Graphic Equalizer -
