Amps for New G chassis BMWs:
Currently we only offer the Stage One and Ghost Subwoofer upgrades for the newer BMW models. Our New Revenant Pro amplifier is not yet compatible with the newer G chassis models.
The G Chassis cars use a new communication protocol to the amplifiers, that there is not yet an adapter available for, which prevents us from offering the Revenant Pro for these models.
Unfortunately, at this point we do not have an ETA for when this will be available. Due to the nature of the development of the adapter it is hard to say exactly when, or even approximately when that may be. Rest assured we would like this out as badly as you, and I apologize that I’m not able to provide a date of when that will be available.
Amps for older generation E chassis BMWs:
Unfortunately, the Revenant amplifier upgrade isn't compatible with your generation BMW and we don't have any plans to make a version for those older model vehicles.
We are not aware of any simple aftermarket amp solutions for the E chassis models as they are a closed system that would require a full rewiring of the the entire vehicle to do an amp upgrade.
The best solution we can recommend is an OEM replacement.
Bang & Olufsen or Bowers & Wilkins audio systems:
Unfortunately we do not have any upgrades compatible with the B&O or B&W audio systems.
The B&O/B&W system is suppose to be top of the line and there aren't many of them made, so we will not be investing time into developing upgrades for them.
For the Bang and Olufsen system, our Ghost subs do fit in the under seat compartment however, the B&O amp signal will cause our subwoofers to blow after mild use. For this reason we cannot offer them as compatible to your B&O audio system.
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.
