Customer Testimonial

I submitted a request for information on connectors for substituting a radio from my newer Dodge van to my older New Yorker. I got an immediate reply from Kirk C. who researched the appropriate connectors for me. Sonic Electronix and Kirk C were the only ones that came through with some help. Thanks
