This vehicle came to Audio Pros completely stocked. Their customer had aftermarket subs and amps from a previous vehicle and wanted to run them off the factory head unit. You could get away using line out converters to provide rca signal, but if you want a high level of controllability the only viable answer is a Digital Signal Processor (DSP).
The AX-DSP from Axxess Interfaces is a great solution because it comes with a handy companion app for advanced sound tuning. 2 sets of Focal plug and play speakers complete the system and provide serious performance with minimal modification.
