Do NOT order a different woofer expecting it to work!
Scroll down for specifics on your vehicle and audio system:
Ghost Subwoofers for: E60 M5, E70/E71 X5M/X6M, E90/E92/E93 M3s with the S752A Individual Audio system
We no longer offer the subwoofer upgrades for vehicles with the S752A individual audio systems. We started to notice regular subwoofer failures with some S752A individual audio systems in the M5s, X5s and M3s and removed them from our offerings in early 2021. The s752a individual amps had a largely disproportionate amount of blown subs compared the other systems. Even after matching the impedances, we could not resolve the issue and therefore had to remove that option from our catalog. Basically, they physically fit and the impedances match but for some reason they tend to blow more easily due to distortion caused by those amps. So we can get you amazingly clear audio from the other speakers but cannot upgrade the bass from your subs.
Ghost Subwoofers for F01/F02 7 series with Premium audio systems:
We found that the 7 series vehicles from 2009-2015 with the Premium amplifiers had a largely disproportionate amount of failures compared the other systems. Even after matching the impedances, we could not resolve the issue and therefore had to remove that option from our catalog. Basically, they physically fit and the impedances match but for some reason they tend to blow more easily due to distortion caused by those amps. So we can get you amazingly clear audio from the other speakers but cannot just upgrade the bass from your subs.
One solution we know of to get you a working under seat subs is to purchase our Revenant PRO amp upgrade which will then allow you to purchase the Bavsound Ghost subwoofers to work with the new amp.
(We can sent a custom invoice that includes the subwoofers and amplifier upon request to sales@bavsound.com)
Otherwise, you will need to purchase OEM factory replacements
