Pros: usb port for ipod/usb devices , aux port, looks cool at night when lit up blue
Comments: really good bass, makes your stock speakers come alive. Works well with ipod and usb. Haven't tried cd player yet, but I am sure it is good as well. It has bass boost, which really makes it sound like you have subwoofers in a stock system. It also has controls for bass, mids, and treble. Great buy, buy with crutch field and get free shipping and installation gear for installation yourself.
