Is my sub broken???
Ok I have a 2013 JKU Rubicon soft top with navigation. I have to say I'm not to impressed with the audio system in it. Even when I turn the bass all The way up I can't notice any bass in my music at all I even tried rap no bass. Does anyone else have this problem. O and another I can't seem to get over 16.8 mpg on the highway. I have a 6speed. Thanks.
