The Interceptor 5000 is the magical backbone of the EVA System! This harness intercepts the power and audio signals from your factory headunit and feeds them into the Digital Signal Processor or DSP. The DSP allows you full access to the sonic spectrum to manipulate the sound in the vehicle to your tastes! After processing, the signal is sent to the amplifier where the circuitry is of a higher caliber and output than the headunit, allowing you to maximise thier potential without having to replace the drivers themselves! What is most unique about the harness is the connection to the DSP. When you go to trade in or upgrade your vehicle, you can take the DSP with you and send us your old harness as part of our UpCycle program in exhange for one made for your new vehicle!
