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.
do not buy any oem audio equipment from Subaru. it will be beyond shitty. you can pay me, ill punch you in the face and that will be a better value. you can buy real stereo equipment for not a lot of money.
if your that worried about putting an amp under the seat, that's where mine is and no complaints from rear passengers, you can put an amp in that foam thing or somewhere else. lengthening the air ducts I imagine can easily be done with some creativity and some supplies from home depot.
