Ok the car is a 1988 Regal. My box takes up the entire trunk therefore, back of seats is a no go and they don't fold down so definatley a no go. The wheel well is out because I need my spare bcuz I have a bad tire and I live in the country so if I get a flat it's me and the road. I also think that they amps would look good on the underside of the trunk lid. Do you think it would harm the audio at all?
