Very nice EQUALIZER for the price it truly went above all my expectations only thing that is useless is the plexiglass top so you can see the inside of it and the lighting will shine through it. But because of mounting the unit you can’t see the top of the EQUALIZER plus I mounted mine into my console. I did a custom install and another thing the positive wire that comes with the unit is useless way under sized for a 12 volt electrical system I upgraded mine to 12 gauge wires and a 14 gauge ground wire. But everyone into stereo systems you will be very satisfied with this equalizer.
