Would a line driver with line outputs into my amps be ok? I would either do that, and use dsp amps or use a separate dsp processor from the line driver into my regular amps. My system will have a pair of 3 way components up front and two subs in the rear.You need a HU/receiver. The mini is only the signal source in this scenario. You have to have a compatible device to use the signal provided by the Apple device.
