im putting a system (12" idq) in my sisters 06 mazda6 and she wants to keep the stock HU. now i know i need a hi/low convertor, but i dont know how to hook it up. ive done a search but it didnt answer it completely and i didnt understand most of it. the amp is a digital audio(made by audiobahn)da2800 and if someone can post a link to where i can buy a good one that will help a bunch.thanks
