“It’s impossible to enjoy music in an air-cooled Porsche,” or “This car is for enjoying engine sounds.”

When replacing the front speakers with the "PORSCHE 911 speaker system 'model 993,'" be sure to include elements that enhance the low-frequency range. The simplest option is to combine it with a powered subwoofer. Option 1 is the most straightforward configuration for installing the 911 speaker system in the 993. It provides a refined sound that reveals new details in familiar tracks. The basic kit uses the head unit's built-in power amplifier to drive the front speakers. Ensure you have a head unit with an internal power amplifier. If the head unit has a subwoofer control feature, you won’t need a separate controller, keeping the cabin clean. The basic kit includes speaker cables from the head unit to the speaker system and wiring for installing the subwoofer in the front trunk.
Optionally, you can combine the power amp kit. If you find the built-in power amplifier lacks sound quality, volume, or power, the power amp kit is a great option. It includes the front speaker system, subwoofer, CFRP power amp mounting board, and all necessary wiring.
② Option 1, when combined with rear speakers, requires a head unit with subwoofer control functionality. This configuration enhances the sound of both front and rear speakers, adding a more musical tone, and allows you to add a subwoofer for more depth. The basic kit for Option 2 includes all wiring, including the rear speakers centered around the head unit.
The power amp kit can also be added as an option. The basic configuration is the same as Option 1, but it includes additional speaker cables for the rear speakers.
③ This is a basic configuration to enjoy the excitement and presence of BassPLUS+ in the 911. A head unit with subwoofer control functionality is required. Additionally, to drive BassPLUS+, combining it with the power amp kit is essential. There are no head units that can control six channels (front, rear, BassPLUS+), so rear speakers cannot be installed. This simple configuration, with the subwoofer and BassPLUS+ extending the musical world towards the front screen, will surely impress you with your first BassPLUS+ experience. Instead of just a vibrating sound, BassPLUS+ blends seamlessly into the music, transforming your listening experience into a true sensory experience.
④ This is a system configuration that adds rear speakers to Option 3 and provides full control through the DSP power amplifier. Since the control doesn’t rely on the head unit, you can even restore the original interior with a factory cassette deck featuring the “PORSCHE” logo, as shown in old catalogs. Imagine standing in front of an interior that’s identical to the one you longed for and admired in those catalogs, filling your car with a music space you’ve never experienced in any luxury saloon, while feeling the Porsche's feedback on the steering wheel... This system configuration brings out the true value of the 911/model 993 yamaguchi speaker system, designed with the intention that you can truly experience this in your own car. Choose from the DSP power amplifier options: A) audison AF C8.14bit, or B) AF M8.14bit. The B) AF M8.14bit option is recommended for its superior sound quality, similar to a high-end analog amplifier, and provides ample power for enjoying music in an air-cooled Porsche. Both models offer six preset DSP sound settings, including options for the driver’s seat, passenger’s seat, and full orchestra, ensuring an enjoyable experience for many. Special custom settings can also be created upon request (for a fee).
For Porsche enthusiasts who stubbornly believe that “you can’t enjoy music in an air-cooled Porsche” or “this is a car meant for engine sounds,” and yet, deep down, love music and have an incredible home audio system―this is the experience you’ve been waiting for. It’s the “yamaguchi speaker system for air cooled 911,” meticulously created as a custom option specifically for air-cooled Porsches, and it’s available for you to enjoy for a whole year.
