Yes, we can handle the installation of tweeters and midrange speakers into the A-pillars, as well as the fabrication of one-off A-pillars. Based on your preferences for sound staging and design, we can help you with anything from a natural finish close to OEM to full custom work. If you tell us the vehicle model, what you want to do, and which units you’d like to install, we’ll let you know whether it’s possible, the approximate cost, and the estimated施工 time. Since the final finish and process may vary depending on the vehicle’s condition and shape, we may recommend an on-site inspection of the vehicle.
