Plug & Play Signal Adapter for Aftermarket Amplifier 14+

Radio Flash & DSP
It is highly recommended to have your radio flashed by an independent bike shop with the proper equipment or to rent a flash tool and flash your bike yourself.

Technoresearch offers several flash options in its software, supplied by various aftermarket amplifier manufacturers. We recommend using the Rockford Fosgate flash. This flash provides a friendly EQ curve for aftermarket amplifiers and speakers. It also enables rear speakers, front-to-back fader (not all flashes do), bass and treble controls, and a speed-dependent volume feature.

Additional Speaker Pod Connectors
This kit includes connectors that mate with your fairing speaker pods, allowing you to connect your aftermarket amplifier directly to the pods without cutting or splicing into the bike's wire harnesses. We always recommend using speaker pod connectors along with our signal adapters.

Front or Rear Signal
This kit is ready to plug directly into the front signal harness of the factory radio on all Harley touring bikes. Optionally, we offer a rear signal version that converts this adapter to fit the 4-pin connector Harley uses for the rear channels on 4-channel bikes.

Note: If you are purchasing this item for rear signal only, you will not need the optional speaker pod connectors, and they will not be included in your kit. Speaker pod connectors are used only for front fairing applications. Rear kits, however, include an adapter compatible with the rear radio outputs.

If you plan to install a DSP, consider adding our Stealth Power Tap Harness, which plugs into the CB radio port, typically unused unless you have the CB radio module. Ultra models often include the CB radio module, but if you don’t use the CB radio, you can easily remove the module to free up the port and space. You can select the Stealth Power Tap Harness as an option below.
