I have a 05 Pontiac G6 GT and I would like to install Subs in my trunk of the car. I have no experience with this. I was wondering if someone could tell me what I am looking for or any suggestions. Also I want to keep my stock radio and still hook up the subs. And I would like to add an Aux port to the radio if possible. The stock radio has an AUX button but no input. Also about the subwoofers in the trunk will they have the same effect as subs in a truck open to the seating of the car. If you can get estimates on how much each thing will cost it will be much appreciated.

Thanks
