Stage 3 - BMW Speaker and Sub Upgrade

Stage 3 Complete Audio Upgrade Kit for Base Model BMWs

Take your BMW's audio to new heights with the Stage 3 Complete Audio Upgrade Kit, designed specifically for Base model BMWs that prefer an all-in-one solution without separate tweeters.

The Kit Includes:

• CSB4.2X Coaxial OR CSB4.2C Component speakers (Front doors)
• CSB4.2X Coaxial speakers (Rear doors/Parcel shelf)
• CSB-8W Musway 2-ohm subwoofers (Under seats)

Important Note:

The subwoofers in this kit have a 2-ohm impedance and require amplification that is 2-ohm stable. Please do not use this kit with the base model audio pre-2019 unless you have already fitted an aftermarket amplifier. The CSB8W subwoofer features an 8" fiberglass cone, providing harder hits and the ability to be driven louder compared to the OEM subs.
