      Quality and Outstanding Products

      I recently purchased this output converter for my 3rd gen Tacoma and installed it to maintain OEM factory head unit and it works like a charm! Wiring is neat and quality. Highly, highly recommend this business! Customer service is a 10 out of 10 as well. Reached out to him via Facebook and he was very responsive and helpful. I told him what I wanted to do and immediately recommended the right product. Follow him on Instagram, Facebook, and YouTube for DIY installs!
