I have a 2016 Chrysler 200S! I have the alpine sound system and have had trouble with the subwoofer vibrating even with low bass setting! It's been to the dealer 7 times and they can not figure out what is wrong! I had a case open with Chrysler and got no help with them! The car audio store says its in open air subwoofer in the back dash! Poor design on Chrysler's part! To put a new subwoofer in the trunk in a box, like it should be is $600! I bought the car for the premium sound and it is terrible! Wish I would have kept my Impala LTZ with the Bose sound system! Actually, I sorry I bought the Chrysler, should have stuck with another GM car! Anyone else have this problem and is there a fix?
