So just for the sake of discussion, although not many z4 owners have been through this, or at least haven't posted about it, let's assume that used z4's are coming to a price point that people will be buying them who may want to do what we are doing by swapping parts and upgrading them. But, for the masses, they may not want to cut into wires. How much impact on quality of sound would be had by the average person swapping out the BT amp, using the revised wiring harness that sends one signal to the kick panel woofers, and being done with it? Did bmw send one signal to those speakers because they are so far into the footwell that they don't have much impact on sound, more just bass? Bavsound's advice was to go into the amp's software and do a low pass filter at 250hz for those midbass woofers. I wonder if doing that would eliminate the problem of muddying up the sound because they would be acting more like subwoofers right? Keep in mind, I know just enough to sound stupid.
