Hey all I don't own a Mazda 3(yet) but my girlfriend does. I'm wanting to surprise her for her birthday by installing a sub into her car. Now I'm not new at this nor am I very experienced with installs but I have a hard time asking people from visions for advice because I'm just a dollar sign to them. Is there anything special that I will need for the amp or wiring kit for the stock deck? If so what am I looking for?
