Well i have 09 fit sport with navi....
my question: im trying to hook up a sub to my car and i want to keep my honda navi unit, what do i need to buy and do ????

 

you need a LOC (line out converter). this allows you to tap into speaker wires and it converts the signal into RCA outputs. the rest is the same. power, ground, remote wires. and then rca signal comes from the LOC.
