Looking for good Car audio shop with reasonable prices.

Take the 106 from Nong Hoi after 1.5 kilometres you will cross over the underpass for the inner ring road. Immediately after the bridge there is a soi to your left the next store along is an audio shop that enters and wins Car audio competitions. They have fitted Pioneer equipment to two of my cars and built and installation for my Lotus. I recommend them highly, limited English but owners and staff helpful. It's an open front store, usually busy with cars having work done.
