My car is a 2012 Civic.
I have a Sony CD player with aux input and Bluetooth.
It powers the stock speakers in the rear dash and a pair of 6.5″ Coustic component speakers in the front doors.
I also have a pair of 10″ Rockford Fosgate subs in a ported box powered by a Kicker ZX-1500.1 amplifier.
I like bass. 🙂
