2015 BMW 4 Series Audio Upgrade
Upon listening to his ‘new car’ this customer decided the sound quality was terrible and he wanted an improvement. After lengthy discussions the customer opted for an Audison AP1 tweeter and an Audison AP4 midrange speaker to replace the factory speakers in the front doors. We didn’t change the speaker under the front seats as this was to be beefed up with an amplifier. The amplifier used for the system was an Audison Prima AP8.9BIT 8 channel amplifier with a built in processor. This amp ran the front under seat speakers bridged and then the 4″ and tweeter were run active.
On the first listen of the car, the customer was blown away with the difference and how easy it was to adjust individual frequencies to tailor the sound to his specific needs.
