[font="Franklin Gothic Medium"][/font][size="5"][/size] Juust Brought The New Fiesta Zetec 3 Door.. In Total I Have 2 Speakers On Each Door At The Front, But In The Back I Have A Cover Of A Speaker But Nothing Behind It. So Was Wondering If A Sub Could Be Installed To The New Car & If It Would Be Hard Work Or Not?
As It Being A New Car I Dont Want To Do Something To Mess The Whole Sound System Up All Together.

Please Give Me Advice On What Too Do, Because The Speakers Are Absolutly Rubbish.
