Plug & Play Signal Adapter for Aftermarket Amplifier 14+

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

Technoresearch has a number of flashes that its software offers. These flashes are all supplied to them by a number of aftermarket amplifier manufactures, but we recommend using the one from Rockford Fosgate. This particular flash has 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 speed-dependent volume feature. 

Additional Speaker Pod Connectors
This kit also comes with connectors that mate to your fairing speaker pods. This way you can connect your aftermarket amplifier directly into your fairing speaker pods without any 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 comes 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 plugs in and converts this adapter to fit the 4 pin connector that 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 in your kit. Speaker pod connectors are only used for front fairing applications. Rear kits do however come with an adapter that makes them compatible with the rear radio outputs. 

If you plan to install a DSP you might want to consider adding our Stealth Power Tap Harness which will plug into the CB radio port, which is generally unused unless you have the CB radio module. Ultra's tend to have the CB radio module installed. However,  if you don't use the CB radio you can easily remove the module to free up the port (and space!). Here is the link to the Stealth Power Tap w/o CB Harness.  *You can select the Stealth Power Tap Harness as an option below.

If you do use your CB radio, you will want to skip the harnesses on this page completely and purchase the Radio T-Harness that you can find here.
