The iconic “Ultimate Driving Machine” slogan might be BMW’s, but for many E90 owners, the factory audio system doesn’t quite live up to that promise. If you’re looking to transform your E90’s audio experience into something truly worthy of the badge, upgrading to a JL Audio system is a popular and effective solution. This comprehensive guide will navigate you through the common issues, solutions, and installation process of a JL Audio upgrade for your BMW E90.
Understanding the BMW E90 Audio System
Before diving into the upgrade, let’s take a quick look at the stock audio setup in the E90. BMW offered several audio system options for the E90, ranging from a basic system to a premium system with features like Logic7 surround sound. However, even the higher-end options often lack the clarity, depth, and power that audiophiles desire.
Common Issues with the BMW E90 Audio System
Several factors contribute to the less-than-stellar audio quality in the E90:
- Subpar Speakers: The factory speakers are often made with low-quality materials and lack the necessary power handling capabilities for a truly immersive sound experience.
- Insufficient Amplification: The factory amplifier is often underpowered, limiting the potential of even upgraded speakers.
- Poor Sound Insulation: The E90’s cabin isn’t particularly well-insulated against road noise and vibrations, which can interfere with audio clarity.
JL Audio: The Solution for E90 Audio Woes
JL Audio is a renowned brand in the car audio industry, known for its high-quality speakers, amplifiers, and subwoofers that deliver exceptional sound quality and performance. Upgrading your E90 with JL Audio components can address all the aforementioned issues, resulting in a dramatically improved listening experience.
JL Audio Speaker Upgrades
Replacing the factory speakers with JL Audio speakers is the foundation of any good audio upgrade. JL Audio offers a wide range of speakers specifically designed for the E90, including component speakers for the front and rear doors and coaxial speakers for the rear deck. These speakers feature advanced materials and construction for superior clarity, detail, and power handling.
JL Audio Amplifier Upgrade
To truly unleash the potential of your new JL Audio speakers, an amplifier upgrade is essential. JL Audio offers a variety of amplifiers with different power ratings and features to suit your specific needs. A dedicated amplifier provides clean and powerful signal to your speakers, ensuring they perform at their best.
JL Audio Subwoofer Upgrade
For those seeking deep, powerful bass, adding a JL Audio subwoofer is a must. JL Audio offers a range of subwoofers in various sizes and configurations, allowing you to choose the perfect match for your E90’s trunk space and your listening preferences.
Diagnosing and Addressing Audio Issues in Your BMW E90
Before you start tearing into your car’s audio system, it’s wise to diagnose any specific issues you’re facing. This can save you time and money in the long run.
Common BMW E90 Audio Problems and Solutions
Here are some common audio problems E90 owners encounter:
- No sound from speakers: This could be due to a blown fuse, faulty amplifier, or wiring issues.
- Distorted sound: This is often a sign of a blown speaker, a problem with the amplifier, or a wiring issue.
- Static or popping noises: This could be caused by loose wiring, a faulty ground connection, or interference from other electronic components.
If you’re not comfortable diagnosing these issues yourself, it’s always best to consult a qualified car audio technician.
Using Diagnostic Software for Troubleshooting
Modern cars, including the BMW E90, are equipped with sophisticated electronic control units (ECUs) that manage various systems, including the audio system. Diagnostic software can be used to read error codes and data from these ECUs, helping pinpoint the root cause of audio problems.
For instance, a diagnostic tool like Cardiagtech can help you identify issues with the amplifier, speakers, or wiring. This valuable information can save you time and money by directing you to the specific problem area.
JL Audio Installation: Professional vs. DIY
Installing a JL Audio system in your E90 can be a rewarding DIY project for those with some car audio experience. However, it does require a certain level of technical skill and knowledge. If you’re not comfortable working on your car’s electrical system, it’s always best to leave the installation to a professional.
Tools and Equipment Needed
Whether you choose DIY or professional installation, here are some essential tools and equipment you’ll need:
- Wiring harness: To connect the new amplifier and speakers to the car’s electrical system
- Speaker adapters: To mount the new speakers in the factory locations
- Amplifier wiring kit: To power the amplifier
- Subwoofer enclosure: If you’re adding a subwoofer
- Basic hand tools: Screwdrivers, wrenches, pliers, wire cutters, etc.
