NAMZ Custom Cycle builds plug-and-play wiring harnesses, extension kits and electrical components for Harley-Davidson. Its handlebar extension and connector kits are what make an ape hanger or bagger bar swap a bolt-in job instead of a splicing project.
The NAMZ Custom Cycle Amp Power Audio Noise kit is a complete integration solution for V-twin motorcycles, designed to convert factory radio speaker outputs into line-level input for external amplifiers. This kit also tackles the common issue of ground-loop noise, ensuring a cleaner audio signal.

Designed for V-twin motorcycle audio systems
Upgrading your Harley-Davidson or Indian Motorcycle audio system often means dealing with factory head units that don't provide a clean line-level output for aftermarket amplifiers. This NAMZ Custom Cycle kit solves that problem with a hi-lo converter, transforming your speaker-level signals into what your amp needs. Beyond signal conversion, it includes a crucial ground loop isolator to eliminate frustrating hums and static, letting you enjoy your music without interference.

Hi-Lo converter efficiently changes speaker-level output to line-level for external amplifier input

Seamless Integration with Factory Radios
Installing an aftermarket amplifier with a factory radio can be challenging, but this NAMZ kit streamlines the process. The included OEM 35-pin rear speaker harness allows for a direct, plug-and-play connection to your stock Harley-Davidson or Indian Motorcycle radio. This thoughtful design minimizes cutting and splicing, making for a cleaner and more professional installation. Note that a dealer flash may be required to activate rear channels for proper functionality.

Must have for your detatch set up
When i installed a detach kit on my 16 Ultra Limited, i had added filler panel lights as well as the saddle bag lights (a lot of connectors and components). I was looking for a solution to the bulky wiring harness for the tail/signal lights when re-attaching my tour pack. I have made a lexan plate/shelf to support the harness and protect the paint on the fender. Now i can leave the bulk of the harness under my seat and the smaller harness sits nicely on the shelf.

Easy Plug n Play!
Excellent harness! This is a plug n play connector! I used this on a 2019 Road Glide Special to connect lighting to a King Tour Pac. I had to purchase the tour pac, wiring harness & lighting separately but this harness made it plug n play.
