About the Helix CI42216
From our tech experts at CEN

It also allows the Ci5 S200FM to fit Land Rover and Jaguar vehicles with factory woofers in the doors. Crimp contacts, housings and mounting material are included.
Who it suits
BMW and MINI owners wanting more bass from the under-seat locations without losing boot space. It is made for the Ci5 S200FM-S2 and Ci5 S200FM-D2 only, both sold separately.
Our tech experts advise
Choose between the S2 and D2 subwoofer based on how your amplifier or factory system will drive them. Under-seat installs need care with seat removal and cable routing, so we recommend professional fitting. Installation is priced per vehicle, so send us your make, model and year and we will confirm fitment.
