The BMW E39, produced from 1995 to 2003, is a highly regarded luxury sedan renowned for its performance, handling, and timeless design. However, like many vehicles of its era, the audio system in the E39 can feel dated by modern standards. If you’re looking to enhance your driving experience, a BMW E39 audio system upgrade is a worthwhile investment.
A lot of car owners look to upgrade their audio systems for a more immersive in-car experience. The BMW 4 Series Coupe audio upgrade is a great example of how much of a difference a new sound system can make.
Understanding the E39 Audio System
The E39 came with several factory audio options, ranging from a basic four-speaker setup to a premium Harman Kardon system. Regardless of the trim level, the factory system suffers from common issues, including:
- Weak bass response: The factory speakers often lack the depth and punch to reproduce low-frequency sounds accurately.
- Muddy midrange: The midrange frequencies, responsible for vocals and instruments, can sound cluttered and indistinct.
- High-frequency roll-off: The high frequencies, responsible for clarity and detail, often sound muted and lack sparkle.
These problems are primarily attributed to the age of the components, the use of lower-quality materials, and the limitations of the factory amplifier.
Common E39 Audio System Problems
Over time, the E39’s audio system can develop various issues, including:
- Speaker failure: Age, wear and tear can lead to blown speakers, resulting in distorted or absent sound.
- Amplifier malfunction: The factory amplifier can fail due to overheating or electrical problems, causing intermittent or complete audio loss.
- Head unit issues: The factory head unit may experience problems with CD playback, radio reception, or display malfunctions.
- Wiring problems: Loose or damaged wiring can cause intermittent audio problems or complete system failure.
“A common mistake that people make is assuming that just replacing the speakers will fix all their audio problems,” says Michael Stevens, author of “The Complete Guide to Automotive Audio Systems.” “The amplifier and head unit play crucial roles in sound quality, and neglecting them can lead to disappointing results.”
Diagnosing E39 Audio System Issues
Before embarking on an audio system upgrade, it’s crucial to diagnose the root cause of any existing problems. You can start by:
- Checking the fuse panel: Ensure that the fuses for the audio system are not blown.
- Inspecting the wiring: Look for loose or damaged wires, especially around the speakers and amplifier.
- Testing the speakers: Use a multimeter to test the speaker impedance and ensure they are functioning correctly.
- Examining the head unit: Check for any error messages or unusual behavior.
If you’re not comfortable performing these tests, it’s advisable to consult with a qualified automotive electrician.
Upgrading Your E39 Audio System
Upgrading your E39’s audio system can involve replacing various components, including:
Head Unit
The head unit is the brain of your audio system. Upgrading to an aftermarket head unit with features like Bluetooth connectivity, Apple CarPlay, and Android Auto can significantly enhance functionality and sound quality.
Speakers
Replacing the factory speakers with high-quality aftermarket speakers can dramatically improve clarity, bass response, and overall soundstage. When choosing speakers, consider factors such as size, power handling, and sensitivity.
Amplifier
An external amplifier can provide the necessary power to drive your speakers and subwoofer, resulting in cleaner sound and increased volume. Choose an amplifier that matches the impedance and power requirements of your speakers.
Subwoofer
Adding a subwoofer to your E39 can significantly enhance the low-frequency response, providing deep and impactful bass. Consider the size and type of subwoofer that best fits your vehicle and listening preferences.

FAQs about BMW E39 Audio System Upgrades
Can I upgrade my E39 audio system without replacing the head unit?
Yes, you can upgrade your speakers, amplifier, and subwoofer without replacing the factory head unit. However, keep in mind that the head unit’s capabilities will limit the overall sound quality.
What size speakers fit in the E39?
The E39 has various speaker sizes depending on the location. The front doors typically house 6.5-inch or 5.25-inch speakers, while the rear deck may have 6×9-inch speakers.
Do I need to recode my E39 after an audio system upgrade?
In most cases, recoding is not required for simple audio upgrades like speaker replacements. However, if you’re installing an aftermarket amplifier or head unit, recoding may be necessary to ensure compatibility and avoid error messages.
“Recoding the car’s computer system after an audio upgrade is essential to ensure proper functionality,” explains Sarah Jones, a certified automotive technician with over 15 years of experience. “It allows the car to recognize the new components and adjust its settings accordingly.”
