okay so I recently just bought a 2004 Mazda 3 hatchback. and my friend wants to sell me his system with two subs and an amp. however I don't want to put a head unit in bc I don't want to loose the steering wheel controls... therefore he told me the car must have "line out" or something like that for it to work. soo can one of you experts tell me if my car has that so I can hook my system up ?
thanks !
thanks !
