Hi there, Im going into the coast guard and to treat myself to an new 09 5 door wrx. (pics later on) But first time owning a new car and esp a wrx so first of many stupid questions lol does anyone know if the stock radio head unit can support a sound system. i.e. 2 twelve's and amp

Any help is greatly appreciated, thanks

 

it doesnt have the plugs you need. If you want to keep the stock deck you need a hi/lo convertor. You tap it into the rear speaker wire and set the level on it. You sacrifice quality with that setup.
