I recently purchased and took delivery of a 2016 GT350 with the standard 4 speaker audio system. Last week I took the car in to have the audio system upgraded by adding new speakers, an amplifier and a sub in the trunk. Driving away from the installer, I noticed engine noise emitting from the left and right front channels as I accelerated. The sound commences at between 3,000 and 4,000 RPMs and fades out above that level. I have read that Ford is piping in engine sounds on the Eco-Boost Mustangs. Does anyone know if this is the case on the GT350s? Was not really an issue with the stock equipment, but with the upgrades it sounds like a hollow-knocking. It only occurs while the car is moving as revving the engine at a standstill does not result in sound from the speakers. I would very much like to turn it off if anyone knows how.
Thanks
