Hey guys I've had my ecoboost for about 7 months now and i finally got around to installing my old system in this truck. The only problem was finding somewhere to hide the amp. (Settled with under the drivers seat) . I wanted to keep the factory stereo because i wanted to keep the SYNC feature. My setup is 2 12 kenwood excelon shallow mounts and a kenwood 1800 watt amp! This is my favorite system that i have had so far. I kept the factory stereo and added a bass knob to control the subs and love it. I was going to get aftermarket speakers but the guy installed them talked me out of it, he messed with some settingsand they sound like aftermarket now! All and all this is a awesome setup and i am very pleased .
