I'm considering upgrading my audio system , but I can't determine what package i currently have. There is one speaker in the middle of the dash. A pair of large speakers behind the seats. One speaker in each door card and one speaker at each front window near the mirror. I can not find any amp in the trunk. And i don't see any sub's under the seat.
My car is a 2011 3.0i M-Sport package.
