Sorry! Unfortunately we do not have any compatible upgrade solutions for the model of BMW you are looking for and we do not have plans for developing them going forward.
Please do not call or email requesting more information!
Our kits are designed and tuned specifically for the vehicle intended. We only recommend using the kit for your exact vehicle through our website's vehicle selection options. So, if it is not listed we highly discourage trying to make another kit work.
This list includes:
BMWs from 1994 and earlier...
BMW E36/37 Z3s & BMW E53 X5
Unfortunately we no longer have any upgrade solutions for the BMW Z3s and E53s. We discontinued the kits a while back and have no plans for developing them going forward. There are just not enough people looking for speakers these days. And the minimum production quantity needed does not justify the cost of us housing the unique speakers for those vehicles that we will never sell through. It is just basic economics, not because we don't like the models!
Any Trunk or Ski Pass subwoofer box setups:
The trunk sub box was a great product however, upgrades such as that required significant technical support time that it wasn't profitable enough to continue. Our business model has since shifted to being a plug and play solution only company.
We don't have a recommendation for trunk subs as that isn't something we have focused on for quite some time. Your best resource for preferred speakers would be the Bimmer forums. For a stealthy box you would need to consult a car audio professional. One option we found through a dealer is the Magic Box shown here: https://shop.wickedcas.com/magicbox/bmw/
Thank you so much for considering Bavsound for your audio needs. We truly appreciate it, and we wish you all the best at finding upgrades for your vehicle.
