BMW Stage 7 Full Audio Upgrade Sound System
This Stage 7 BMW audio upgrade is a complete plug-and-play sound system package for customers who want a full system improvement rather than changing one part at a time. It combines front speakers, rear speakers, underseat woofers, a Musway DSP amplifier and vehicle-specific plug-and-play wiring.
The aim of this kit is to give your BMW a stronger, cleaner and more detailed sound while keeping the installation reversible and avoiding cut factory wiring.

Installation and setup
This kit is designed for BMW owners who want a high-quality upgrade without custom fabrication. A confident DIY installer can fit this type of system, or it can be installed by a professional car audio installer.
For best results, the DSP amplifier should be set up correctly for the vehicle and speaker layout. Contact Tender Sounds if you need help choosing the correct option or want advice before fitting.
Vehicle compatibility
This kit is intended for selected BMW and MINI vehicles using compatible BMW-style speaker and underseat woofer locations. Compatibility depends on the exact model, year and factory audio system.
Common BMW platforms include selected 1 Series, 3 Series, 5 Series, 6 Series, 7 Series, X1, X3, X5, X6, Z4 and M models. Because BMW audio systems vary, please send your VIN or registration if you are unsure.
Before ordering
- Check whether your car is Base Audio, HiFi 676 or RAM 2019+
- Send us your VIN or registration if you are unsure
- Confirm whether your vehicle already has tweeter locations fitted
- Ask us before ordering if the vehicle is leased, financed or must remain fully reversible
