Ultra Hi-Fi Sound Question: just got my 2016 TMS 90D that should have Ultra Hi-Fi Sound, but I thought I read there is a subwoofer in the trunk area, but in my car there is not one. Anyone with Ultra Hi-Fi Sound in their car, and has a subwoofer could you let me know, maybe post a pic or maybe I was wrong.... I tried to search the form for a picture or thread but could not find anything. Thanks!
