Recommend you Don't Do It! The low frequency from the Bass will cause your car to develop permanent rattles and squeaks,....and when it comes time to resale! Most will walk away from your car thinking that it's junk! Now, if you don't consider the e60 M5 an investment,...then by all means,..tear it up as you please!
