***If installing multiple amplifiers, or using a 5 channel amplifier that doesn't have internal summing for the subwoofer channel (needs a dedicated subwoofer input only), you may need an RCA splitter(s) if ordering a 4 channel LOC kit.

      Fantastic Product and Service

      I have a 2015 Tundra with the non JBL system and wanted to do the installation myself. The harness and customer service I received from Chris allowed me to make that happen. The process was easy. I found a YouTube video that lead me to this site. I had the harnesses in two days with personalized installation instructions. It was literally plug and play.

      I would highly encourage anyone looking to upgrade their systems without cutting into any factory harness to try this companies products.

      I ordered the NVX XLOC66X Wiring harness and Chris delivered a very nice setup. His plug and play harness is why I decided to try putting a mild system in my truck. Chris replied to emails and messages on messenger. Look if you want build a system and you’re not sure about how to like me, watch his videos, buy a harness and ask for advice. He will respond and I think his harness’s are worth it especially if your inexperienced like me with this stuff. I’ll post another review when I get it done.
