I bought this to do a custom install for a radio on my side by side. The radio itself did not have a CD in the body of the radio itself was only about one and a half to two inches deep and was going to be mounted in and under the cabinet style single den radio housing. this little amp is so small that I was able to install the radio and the amp itself inside an average size stereo housing. It was easy to install it works well in the sound and power output is much better than the small radio itself. Good value for the money I'm happy with my purchase I would likely purchase again if needing something very small.
