Compatibility, installation and tuning
This is a standalone signal processor, not an amplifier. Compatible external amplifiers, speakers, wiring and vehicle integration are required. The HEC expansion modules and optional controllers are sold separately; Bluetooth and USB audio-streaming modules are not included. The supplied USB cable is for configuration, not a promise of built-in USB music playback.
Contact for install price. Supply only. Please send your vehicle make, model, year and existing audio details for installation and tuning advice. Additional parts or labour depend on compatibility and installation circumstances and will be quoted and agreed before work starts.
