A client from San Jose recently contacted the team at California Car Sounds and Tint to inquire about adding a subwoofer to his 2007 Porsche 911 GT3. The client had been in a month earlier for a radio upgrade, and now he wanted to improve the realism of the sound system. After inspecting the vehicle and taking into consideration how it’s used, our fabrication team proposed a unique front-mount subwoofer solution.
Making a New Car Radio Sound Even Better
The client had us install a Pioneer AVH-4500NEX multimedia receiver in his 911 so that he’d have modern technologies like Apple CarPlay and Android Audio. The new radio also allows the client to stream music from his smartphone or play his MP3 digital audio files from a USB memory stick.
The client liked the features of the radio but decided that he wanted to the audio system to sound better. He already owned a JL Audio 8W7 8-inch subwoofer and a JL Audio XD600/1 monoblock amplifier. He hoped that we could use these components to upgrade the 911. Knowing that the client takes the car to the race track, we had a better option for a subwoofer.
High-Performance Porsche 911 Subwoofer Design
Our fabrication team set to work measuring and cutting pieces of MDF to follow the shapes of the footwell. Each of the panels includes unique angles that allow them to come together into sort of a triangular prism. We added bracing along the internal joints for added strength, then finished the interior with a layer of resin-impregnated fiberglass. The fiberglass not only adds strength to the joints between the panels but ensures that the enclosure is airtight so that the subwoofer will sound great.
A set of heavy-gauge metal mounting brackets allowed us to bolt the subwoofer enclosure to the vehicle, keeping the enclosure secure during the high cornering and braking force that naturally come with time on the track.
Amplifier Upgrade Delivers Performance
We mounted the XD600/1 amplifier behind the driver’s seat to keep it safe and secure. It provides an impressive 600 watts of power to the sub. With the main speakers in the car running on the small amplifier in the radio, this is more power than the client needs. He told us that he planned on upgrading the system further with an amplifier for the speakers and maybe upgrading the speakers at the same time. Once that’s done, this system will really come to life.
For now, the client is very happy with the performance of the custom subwoofer system in his Porsche 911.
