MARANTZ

Services

GNP offers service on a wide range of products. We specialize in, but are not limited to, the products we represent. We are also an authorized service center for most of the brands we carry, and even have a few tricks up our sleeves if you are interested in performance-improving modifications or need custom cables made.

Planning a new home theater or in-house audio system? We can help you piece together the right equipment and design a system based around your specific needs. We can even connect you with a couple of contractors to expedite the whole process. The only thing you have to do is call. 

Complete Repair Service is now provided from Donnie's home in Monrovia.  Please see CONTACT page.
