BMW 4 Series Car Audio Upgrade Review - AVI Speakers

Elevate Your BMW 4 Series Convertible's Sound Experience

Many BMW 4 Series convertible owners, whether new or long-time drivers, seek to enhance their vehicle's audio system. The desire is to match the exhilarating open-top driving experience with equally impressive sound quality. This review details a car audio upgrade for the BMW 4 Series, focusing on the installation of AVI speakers.

Why Choose AVI Speakers for Your BMW 4 Series?

AVI speakers are a popular choice for BMW 4 Series audio upgrades because they are specifically designed for the vehicle. This means they fit perfectly into the original speaker locations without requiring modifications, preserving the car's interior aesthetics. This plug-and-play nature simplifies the installation process significantly.

Noticeable Improvements in Sound Quality

The most significant difference experienced after upgrading to AVI speakers is the enhanced soundstage and clarity. Unlike the often flat sound profile of stock systems, AVI speakers deliver distinct lows, crisp highs, and well-defined mid-ranges. This creates a more immersive listening experience, akin to being at a live concert.

Installation Process: BMW 4 Series Car Audio Upgrade

Replacing your car's audio system is more than just swapping parts; it requires precision to avoid damaging your vehicle. The process involves careful door panel removal, old speaker extraction, new unit installation, and meticulous reassembly.

Step 1: Initial Inspection and Door Panel Removal

The process begins with a thorough inspection of the vehicle's interior, checking the door panels for any existing damage and ensuring the speaker area is free from moisture or debris. The door panels are then carefully detached to access the factory speakers.

Step 2: Speaker Replacement

The original speakers are removed, and the new AVI speakers are installed. As these are BMW-specific, they fit precisely without the need for custom fabrication. Wiring connections are made carefully, ensuring compatibility with the car's existing electronic systems.

Step 3: Door Reassembly and Sound Tuning

Once the new speakers are securely in place, the door panels are reassembled. It's crucial at this stage to verify all wiring is correctly connected and the speakers are stable. Finally, the sound system is tuned to optimize the audio balance, with multiple tracks played to test the new sound quality.

The Result: A Transformed Driving Experience

Post-installation, the difference in sound is immediately apparent. Bass frequencies are richer, and mid and high frequencies are significantly clearer. Many owners report reduced listening fatigue during long drives, making the experience more enjoyable. This high-quality audio complements the sporty and luxurious feel of the BMW 4 Series, enhancing its overall value and the driving pleasure.

Cost and Timeframe for Upgrade

The cost for an AVI speaker upgrade for a BMW 4 Series typically ranges from ₩800,000 to ₩1,500,000 (approximately $600-$1100 USD). The final price depends on the specific speaker model chosen, whether front and rear speakers are replaced, and if any additional sound deadening is included. Installation is usually completed within a single day, taking about 3 to 5 hours including sound tuning.
