Audi A5 Subwoofer Upgrade

Looking to upgrade the sound system in your Audi A5? We have just the solution for you! Our team at Soundtech has come up with yet another fancy way to upgrade Audi’s sound system with a 10″ subwoofer in the boot without losing its space.


We used a perfectly engineered MDF prefabricated sealed subwoofer enclosure made to fit this Audi A5 Sportback model to upgrade the vehicle with a nice and powerful 10″ subwoofer driver that greatly supports the existing speaker system. The 250W subwoofer unit was installed to the right-hand side of the boot, perfectly lined up with the rest of the boot’s trim work. Even the cigarette socket was retained, so you don’t have to worry about losing any functionality.


To keep the assembly nice and neat, we used the opposite side of the boot hidden compartment to install the 3 channel amplifier for the new gear. The speakers were German 8″ components from Audio System R series, 125W RMS to match Audi’s 8″ door speaker hole.


We ensured that everything was installed as plug and play, without voiding the warranty, and made it possible to restore the original setup with no trace left. We take pride in ensuring that our installations are clean, professional, and top-notch.


One of the benefits of this upgrade is that it does not take up any additional space in your car. The subwoofer and amplifier are installed in a way that is non-intrusive and does not compromise on the functionality of your car’s boot space.


The results of this upgrade are truly remarkable. The bass is much more powerful and the sound is much clearer, making for a much more enjoyable listening experience. The sound system has been fine-tuned to perfection, and the stage has been precisely tuned up with the sound image oriented for the driver’s seat.


At Soundtech, our team has been factory trained and licensed to install these systems, so you can rest assured that you have the very best working on your vehicle every step of the way. We are committed to providing you with the best quality and service possible, and we take great pride in our work.
