2005 BMW 3 SERIES E90 AUDIO UPGRADE
After purchasing his BMW 3 Series E90, the owner quickly realised that the factory system lacked both clarity and low-frequency impact.
Seeking a noticeable improvement without sacrificing boot space, he turned to Source Sounds for a tailored solution. A JL Audio 10” subwoofer was installed into a custom side enclosure, carefully trimmed to integrate seamlessly within the original boot layout. Power is delivered by a JL Audio 500/5 amplifier, neatly mounted against a bespoke carpeted panel to ensure a clean, OEM-style finish.
The result is a well-balanced system with improved depth, control and overall volume, transforming the in-car listening experience while retaining everyday practicality.
