i was looking for a CD head unit, and this is one of the store I visited. There are actually 3 stores around my area and I visited the one store in San Gabriel. Like most of other audio stores, this one also has a great selection and many new models avaiable. The price was average compare to other audio stores, but I was told the some price includes the installation as well. Since I know how to install a head unit myself, I chose rather get a head unit cheaper rather than include price that is part of installation.
