Hey guys just thought I would hit the forum for some advice, On my 2015 Ecoboost premium it came with the shaker pro upgrade and although the sound is great on it i feel like my speakers dont output as mutch sound relative to the volume level that appears on the screen. While using Bluetooth and playing a song i have my phone turned all the way up and adjust the volume on the sync 2 almost 85% full to get the full effect of the speakers. It feels like they are underperforming or just not enough power is getting to them i would adjust the volume on the sync 2 to max but i don't want to damage the speakers. For comparison i hoped in my dads car witch has a Sync 2 as well. its an upper end ford explorer and set my Phone volume high while the volume on the Sync 2 was set to 50% and outputs A hell of a lot more sound relative to the volume meter where as in my mustang to get the same amount of sound output i think i would have to set the volume to at least 90%. Is it possible my factory amplifier is **** or a blown fuse causes the sound system to underperform. The only electrical work done to the car was when i first purchased it the wire Harness at the bottom of the passenger seat burnt out causing the heated and cool option for the seats not to work but it has been fixed. Oh and im pretty sure none of the speakers are blown i don't hear any raddling or distortion from any side of the car.
