Built for Harley Touring DSP Control The Cicada DSP412PRO is built for Harley-Davidson touring installs where clean signal management matters. A loud motorcycle audio system is not just about speakers and amplifiers. The DSP controls how the signal is routed, filtered, equalized, delayed, and delivered to each amplifier channel. For Harley bagger audio builds using fairing speakers, lid speakers, lower speakers, tour pack speakers, midbass, horns, subwoofers, or multiple amplifiers, the DSP412PRO gives the system the control needed to stay cleaner, louder, and more balanced while the bike is moving. Plug-and-Play Integration Support With the correct plug-and-play integration path, the DSP412PRO can be used with stock Harley-Davidson radio systems to create a cleaner, more controllable signal path for aftermarket amplifiers and upgraded speakers. This DSP can support Harley 2014–2023 stock-radio systems and newer 2023 CVO / 2024-Present Harley touring platforms when paired with the correct integration hardware and system plan. If you are unsure which harness or DSP path fits your bike, contact Garage Bagger Stereo before ordering.

Designed Around Real Motorcycle Audio Motorcycle audio tuning is different from car audio. Wind noise, speaker placement, fairing reflections, lid speaker output, road speed, and helmet interference all matter. A proper DSP setup helps the system stay controlled and listenable in real riding conditions. Recommended System Planning To get the best performance from the Cicada DSP412PRO, match it with the correct radio integration path, clean signal input, proper amplifier layout, correct speaker wiring, and a real tuning plan. For Harley-Davidson Touring and custom bagger audio systems, DSP setup should always be planned around the speaker locations, amplifier channels, crossover points, output levels, and final sound goal. If you are unsure whether this DSP is the right choice for your Road Glide, Street Glide, CVO, Road King, Indian, or custom motorcycle audio build, contact Garage Bagger Stereo before ordering.

Cicada Audio HDTSLINKAR-B 2014–2023 Harley Factory Radio T-Harness
Vendor:Cicada Audio2014–2023 HARLEY FACTORY RADIO INTEGRATION Cicada Audio HDTSLINKAR-B 2014–2023 Harley Factory Radio T-HarnessNo stock radio Flashing Required! Integrate a compatible four-channel aftermarket amplifier with the factory radio in a 2014–2023 Harley-Davidson Road Glide or Street Glide without cutting or splicing the motorcycle’s factory wiring. Removable RCA connectors support conventional aftermarket amplifiers, while the built-in four-position Molex connector provides a cleaner direct connection to Cicada Audio amplifiers. View Connection Options Verify Harley Fitment One Harness for Complete Audio Integration Fits compatible 2014–2023 Harley Touring motorcycles Road Glide and Street Glide applications Factory-amplified and non-amplified systems Basic through CVO Ultra factory audio systems Designed for four-channel amplifier integration Removable RCA output connectors Four-position Cicada amplifier Molex connector Balanced factory-radio audio signal Maestro AR ready included Retains supported factory fade operation Retains supported handlebar audio controls No factory-wire cutting or splicing Updated Replacement for the Cicada HDTSLINKv2 The HDTSLINKAR-B replaces the previous HDTSLINK and HDTSLINKv2 factory-radio harness with a more flexible amplifier connection system. The updated removable RCA connections allow the harness to integrate with compatible four-channel amplifiers using conventional low-level RCA inputs. Installers using Cicada Audio amplifiers can instead use the built-in four-position Molex connector for a cleaner direct connection. This dual-connection design removes the old limitation that prevented the previous harness from connecting directly to certain amplifier platforms. Correct fitment: This updated harness is for 2014–2023 Harley-Davidson Road Glide and Street Glide motorcycles. It is not the correct A2B interface for 2023 CVO or 2024-Present Touring motorcycles. Harley-Davidson Fitment 2014–2023 Road Glide Supports compatible Road Glide factory-radio systems within the 2014–2023 Harley Touring platform. 2014–2023 Street Glide Supports compatible Street Glide factory-radio systems within the 2014–2023 Harley Touring platform. CVO and Ultra Systems Designed to support compatible basic, factory-amplified, non-amplified and CVO Ultra stereo configurations. Confirm the complete audio configuration: Verify the motorcycle year, exact model, factory radio, factory amplifier, fairing-speaker locations, rear-speaker locations and existing audio modifications before ordering. Two Amplifier Connection Options Removable RCA Outputs Use the removable RCA connectors to feed a compatible four-channel aftermarket amplifier with traditional low-level RCA inputs. Cicada Molex Connection Use the built-in four-position Molex connector for direct plug-in integration with compatible Cicada Audio amplifiers. Provides front and rear four-channel audio integration. Supports compatible fairing and rear-speaker configurations. Reduces unnecessary adapter harnesses and connection points. Maintains a cleaner factory-style installation. Allows the same primary harness to support multiple amplifier platforms. Amplifier input verification: Confirm the selected amplifier accepts the available RCA or Cicada Molex connection before beginning installation. Factory Radio and OEM Control Retention The HDTSLINKAR-B is designed to provide a clean audio signal from the original Harley-Davidson radio while avoiding unnecessary changes to the motorcycle’s factory CAN-bus wiring. Factory Fade Support Retains supported front-to-rear fade operation when the complete audio system is wired and configured correctly. Handlebar Controls Maintains supported factory handlebar audio adjustments through the original radio system. Factory EQ Integration Supports factory EQ operation and Maestro AR integration for systems requiring radio-EQ correction or flashing. Maestro AR Integration Cicada identifies the HDTSLINKAR-B as Maestro AR ready for compatible systems using ADS Maestro AR to flatten or flash factory radio EQ settings. Cicada’s current package listing states that Maestro and AR are included. Confirm the exact Maestro hardware and accessories contained in current inventory when receiving and fulfilling the product. Programming may still be required: Maestro-supported radio flashing, EQ correction and module configuration must be completed according to the requirements of the motorcycle, radio and final audio system. Multiple Harness Functions in One Assembly The HDTSLINKAR-B combines the functions that previously required several separate adapters, power taps and speaker harnesses. Front Signal Integration Provides the required front factory-radio signal path for a compatible aftermarket amplifier. Rear Signal Integration Supports rear audio signal routing for compatible saddlebag, lid or Tour-Pak speaker systems. Accessory Power Connection Replaces the need for a separate stealth accessory power-tap harness in supported installations. Rear Speaker Wiring Provides the rear speaker wiring path required for compatible bag or Tour-Pak audio configurations. Battery and Ground Tap Consolidates supported battery and ground integration functions within the primary installation package. Fairing Speaker Pod Adapters Replaces separate fairing-speaker pod plug adapters in supported factory speaker configurations. Recommended Audio-System Applications The HDTSLINKAR-B provides its most complete integration benefits in four-channel Harley Touring audio systems using both front fairing speakers and rear speakers. Fairing and Saddlebag Speakers Supports systems using front fairing speakers and compatible saddlebag-lid speakers. Fairing and Tour-Pak Speakers Supports compatible Ultra systems using front fairing and rear Tour-Pak speaker locations. Four-Channel Amplifier Systems Designed around the signal and speaker-routing requirements of a conventional four-channel amplifier installation. Installation and Ordering Notes Disconnect the motorcycle battery before beginning installation. Confirm 2014–2023 Road Glide or Street Glide fitment. Identify whether the motorcycle is factory amplified. Confirm all factory and aftermarket speaker locations. Verify the amplifier uses compatible RCA or Cicada Molex inputs. Route harness wiring away from sharp edges, heat and steering movement. Secure all unused connectors against vibration and moisture. Confirm left, right, front and rear channel assignments before final assembly. Set amplifier gain and crossover controls after signal integration. Test fade, balance and handlebar controls before reinstalling the fairing. Not for current A2B motorcycles: A compatible A2B interface is required for 2023 CVO and 2024-Present Harley Touring factory audio systems.
