BMW Basic Sound F/G Gen - Speaker & Subwoofer Upgrade Package | HELIX Ci3 / Ci5 (front tweeters pods required)

Overview If your BMW was delivered with the standard "Basic" factory audio system, it lacks the crisp high-frequency definition, midrange separation, and deep low-end punch that a luxury vehicle deserves. The BMW Basic Sound Speaker & Subwoofer Upgrade Package (Front Tweeter Pods Required) is an elite, all-inclusive overhaul designed to transform your cabin into a mobile concert hall. Utilizing Audiotec Fischer’s cutting-edge Helix COMPOSE Ci3 and Ci5 vehicle-specific platforms, this bundle completely swaps out the dull factory drivers in your front doors and floor cavities, replacing them with high-fidelity, high-efficiency components that fit beautifully behind original grilles. Key Benefits Optimized for Base Head Units: The voice coils and high efficiency of the Helix COMPOSE line are engineered specifically to extract maximum performance and clean volume directly from the standard factory BMW head unit without needing an external amplifier. Studio-Grade Front Stage: Adds high-definition 1" silk dome tweeters and precision 4" midranges to your front doors, lifting the soundstage and delivering vocal clarity that was previously non-existent. Tactile Underseat Bass: Features 4-Ohm underseat subwoofers engineered to maximize low-frequency response within the compact factory floor enclosures, replacing muddy tones with tight, accurate bass. Invisible Fitting System: Every driver integrates flawlessly using model-specific Helix FlexMount adaptors for a completely stealthy, original-looking finish. Installation While this premium package features advanced Plug & Play connection harnesses and vehicle-specific mounting brackets, safely removing modern door cards and seating requires professional expertise. At our Rockdale workshop, our team provides meticulous premium installation services, ensuring the new component stage and underseat woofers integrate seamlessly into your BMW's unique acoustic environment. 📦 Available for online purchase through MC Audio Sydney.
