Customer Testimonial

SONIC has the best prices, and fast shipping. This was my second purchase. This time I got new Front & Rear speakers for my truck. I installed them the day they arrived and they sound great. No need to ever go anywhere else looking for equiptment.

Bought this to replace in my 01 Honda civic. I drive 90 miles round trip to work everyday, so I wanted something good but cheap. This is a great CD player... Well worth the money. Wish it came with a hard shell case for detachable face.

This thing is legit. Great sound quality plus many features to change the way you listen to different types of music. I also like the blue or green button light function. I use the green at night because the blue is pretty bright and use blue during the day cause green isn't quite bright enough. Love this thing. Had it for a couple months now.

This Sony CDX-GT640UI is the best head unit I have owned. I love how it is easy to use and the technology it uses makes the music sound a heck of a lot better. The DSO feature actually works and makes not just your iPod music but your radio music have a fuller sound. It really is a fantastic buy.
