Installed within the vehicle's door audio system, the woofer is responsible for reproducing the lower-frequency portion of music and other audio. It works together with the vehicle's higher-frequency speakers to provide a balanced sound across the audible range.

As the original speaker ages, its cone, suspension, voice coil or electrical connections can deteriorate. Common symptoms include distorted bass, buzzing, rattling, reduced output or complete loss of sound from one side of the vehicle.

Replacing a failed speaker with the correct Genuine Porsche unit helps restore the original audio balance and retains compatibility with the factory speaker mounting, wiring and audio-system specification.

What This Product Does:
The woofer reproduces low-frequency sound from the factory Porsche audio system.

Its main functions include:

• Reproducing bass frequencies.
• Adding depth and weight to music.
• Working with the dashboard and mid-range speakers.
• Maintaining balanced left-to-right audio output.
• Reproducing lower-frequency instruments accurately.
• Providing greater fullness at normal listening levels.
• Maintaining the intended factory sound-system character.

• Distorted bass.
• Buzzing noises.
• Rattling.
• Crackling.
• Popping.
• Weak bass response.
• One side sounding quieter than the other.
• No bass from one door.
• Complete loss of sound.
• Intermittent sound.
• Sound cutting in and out.
• Distortion increasing with volume.
• Mechanical scraping noises.
• Speaker vibration sounding uncontrolled.

• Proper bass response.
• Balanced left-to-right sound.
• Clear audio reproduction.
• Reduced buzzing and distortion.
• Correct factory speaker operation.
• Original Porsche audio-system performance.

A defective woofer can affect the entire listening experience even when every other speaker remains functional.
