Great eq for my truck
I had a Planet Audio equalizer that worked good but on the sub frequency only went down to 45 htz. Sometimes for a small truck 45 htz was too much now i can dial it back to 30 htz . Perfect for a small space. I am happy.

Parametric EQ.
This is my second one , NO ! No problems. It just got sold with the last car. Some buy top name brands to little or no effort to their music . For this price and qaulity , name brand " WHO ?" If your like me , you groove to your own beat of your soul . They put together a heap of a balance with this one....Kicking it loud and proud and if it's too loud , well , looks like your too old and I'm 50 going on 24 again.... Let the beats bump..... If you can't get , that's because I'm in heaven with the clarity this thing puts out. Don't believe me ? Try it for yourself...Mr. Ytakeher ! Cause know one else will.......
