I have an 08 Saturn outlook with the upgraded sound system and to be honest, it sucks! I am an ex-car audio installer, and to be honest I shouldv'e used the money for the factory sterio upgrade and got my own aftermarket equipment. A sub should never be in the front of the vehicle, you don't get good separation between mids and highs. Anyways, my question is, does anyone know where the factory amplifieer is so I can tap into the highlevel input so I can run a seperate amp for a new sub enclosure?
