Can the under seat sub be installed on a 2012 premium with the non HK radio with no nav? Is the head unit equipped for it? I like my head unit and the radio isnt on the top of my list of things to change. Just would like a little more bass.
Ill defiantly look into that thanks. I saw your sub woofer on crutchfields site and was considering it. How long did the install take you? Hopefully it works with the stock head unit, i see you put a different one in.
