This product fit right in with my entire boss audio system. I mainly used this equalizer to tune my 10 inch boss phantom subwoofers down so that they would sound at their best when adjusted from my head unit, without having to much bass. the price was good, the design is cool! its all about knowing how to work with what you buy. for having a custom built, self installed $365 system in my 08 single cab f150, I can proudly say my system sounds a whole hell of a lot better than a lot of those "MEGA BUCK" systems. this product made a good addition to my sound quality in my truck.
