I just noticed that my 2017 Grand Cherokee Limited does not have the subwoofer like it did for my 2014 Limited. For my 2014, it was located on the passenger side rear cargo area. However I did see some 2017 Limiteds on Cars.com have it which also indicates under the features section "9 amplified speakers/subwoofer". Looked up my similar Limited on Cars.com without subwoofer and under the features section stated "6 speakers". I guess I have the standard stereo but it seems as though there is plenty of base like the 2014 I had with the subwoofer. So perhaps no subwoofer but better amplifier than the 2014? Either way, the stereo does sound good. I guess I'm wondering why some Limiteds have the 9 speakers/subwoofer and others only have the 6 speakers.
