A client came to us with some equipment he had pulled from a prior vehicle looking to have it installed in his new 2014 F350! We hooked our real-time analyzer and our oscilloscope to his existing Ford Sony system. After some testing, we determined that the AudioControl LC7i would be a good choice to interface with the factory system. The AudioControl piece helped re-combine all the different factory signals together so the amps would have a good full range signal to work with.
The Memphis amps really brought the factory speakers to life, and the JL Audio TW3 12″ shallow subwoofers gave it the bottom end it was lacking before. The client was thrilled with the result.
