My current Sony CDX f7715x has 7 band equalizer and subwoofer controls high low pass filters been very cumbersome to change settings on the fly. With the Skar Ska7eq Equalizer very easy to make quick adjustments to different sound sources and different music. It has definitely improved the sound quality in my system. And for price it won't be beat!!! Very happy.
Easy to install. You’ll love tweaking your sound with this 7-band equalizer. The ease and control of this eq is great!
