Being an audiophile, this client was not happy with the overall sound quality of the factory equipped BOSE system in his new Macan. We have built plenty of other vehicles for him so he knew what he was looking for. While he was happy with the amount of bass the factory subwoofers produced, he was disappointed with the overall tonal quality of the front stage. We easily fixed this by replacing the factory dash mounted tweeters with a pair of Hertz Mille ML280.3 tweeters. For further enhancement we also replaced the factory door mounted 4" midrange with a pair of Audison Prmia 4". To help improve the front impact from the factory 8" door mounted woofers, we sound deadened the front doors as well. These few upgrades made a world of difference in the way the car sounds.
